Ranked in these QuestionsQuestion Ranking
Pros
Pro Wide choice in desktop environments
Debian offers stable and testing CD images specifically built for GNOME (the default), KDE Plasma Workspaces, Xfce and LXDE. Less common window managers such as Enlightenment, Openbox, Fluxbox, GNUstep, IceWM, Window Maker and others can also be installed.
Pro Standard vanilla Linux desktop
Debian runs standard Gnome, XFCE, KDE - it doesn't use its own special desktop environment or debian specific modifications or customisations, which means that users benefit from the work of the whole Linux community, Debian developers can focus on the distribution itself, and any support for your desktop environment on other distributions should work on Debian as well.
Pro Wide choice of hardware platforms
Debian has the widest choice of hardware platforms, including:
amd64, armel, armhf, i386, ia64, kfreebsd-i386, kfreebsd-amd64, mips, mipsel, powerpc, sparc, s390, s390x, source, multi-arch.
Pro Very stable
Debian has a Stable branch, where packages are thoroughly tested before release. Furthermore Debian is know to be the definition of stable when it comes to production systems.
Pro Install and forget
Once installed you can almost forget about it and start to use your desktop for your daily tasks.
Pro Easy to find help with any problem
Debian is one of the oldest and most popular distros out there. Debian's popularity means that you will always be able to find a solution for your problem just by searching on Google, or if by chance nobody has had the problem you are having it's very easy to ask the community and quickly get a solution.
Pro Comes with over 55.500 packages
Because of its popularity, Debian has a lot of applications available which range from productivity programs to business software, games and development tools. It comes with over 55.500 packages (software that is precompiled and ready to be installed on a local machine) -- all of them for free.
Pro Highly secure system
Known for being consistent in maintaining a highly secure system. Several other popular distros use Debian as a base or core for their own Linux OS, the security being one of the main factors why it's so commonly used.
Pro Rolling or Release based
Every Debian Release can either use a Rolling or Release based model.
Pro Well-working team
The developer works very well so the the code is one of the best written out there.
Pro A lot of ways to install software
You can either use aptitude, apt or apt-build to install software from the Debian package archives.
Pro Great for gaming
As Debian is the base for SteamOS and because Ubuntu is based on it, it's almost certain that all Linux games will run properly and require no hacks like creating symbolic links because of some hardcoded paths.
Pro Big open-source project
The Debian project is one of the biggest open source projects with over 5000 active contributors.
Pro Supports SecureBoot
You don't have to disable SecureBoot if you use it, which is useful for LiveUSB or dualboot setups.
Pro The Debian Social Contract
Guaranteed commitment to adherence to values, principles, priorities, requirements and guidelines by the Debian project.
Pro A real installer
Unlike other distributions that just extract their Live image, Debian offers a real traditional and modular installer to customize the installation.
Pro Strict separation of non-free software
Debian is one of the few distros that let the user choose if he wants a free system or not.
Pro Debconf
Depending how it is configured debconf does the most of the hard work for you and only asks you with configuration /file conflicts.
Pro Widely supported
Almost any software that is available for Linux provides a Debian package.
Pro Many ports
Debian supports almost any Kernel maintained CPU instructions set. It has also a few non Linux Ports.
Pro Apt-build
It is possible to rebuild the entire system and optimize it for your hardware (of course, it is not as detailed as Gentoo's USE flags).
Pro Unique release cycle
The most Linux distros have one or two stages before a release, but Debian has five before a new stable version is released (experimental > unstable > testing > code-freeze/bug hunting > stable).
Pro TUI installer
The Debian installer can still be launched as text/curses-like installer which is more compatible and keyboard-friendly than the graphical version.
Pro Standard archives
Debs are normal ar and tar archives with shell scripting and additional gz, bz, lzma or xz compression.
Pro Live install images for CDs, DVDs and USB thumb drives
Debian releases live install images for CDs, DVDs and USB thumb drives, for the i386 and amd64 architectures, and with a choice of desktop environments. These Debian Live images allow the user to boot from a removable media and run Debian without affecting the contents of their computer.
Pro Wise release model
Debian stable does not update a lot and instead provides stability and well tested softwares. You don't get distracted by every shiny new stuff that comes out, and focus on what matters: productivity and reliability of your system.
Pro Debian Fast Track for stable
Stable gets backported software from here.
Pro Great choice for returning Linux users
If you haven't used Linux for a long time, say 5-10 years, it's a great distro in which you can quickly get in the boat again. You don't have to worry about falling back. Everything is in its place.
Pro Has small amount of today's bugs (e.g. no duplicate web cameras in Skype - likely not Skype's fault)
But has quite a few bugs from 2016-2017, apparently for long term.
Pro Familiar user interface
Mint is highly recommended for both users coming from Windows, as well as users coming from Ubuntu, but unhappy with Ubuntu's recent, rather dramatic interface changes. Mint provides an updated interface with a look and feel similar to Gnome 2, with an application menu reminiscent of the Windows 7 Start Menu, with categorization and search.
Pro Already functional out-of-the-box
Mint comes bundled with software for browsing the web, editing pictures, browsing files, watching videos and even a full office suite (LibreOffice). An average user can use Mint right away after a fresh install, using all the software that comes with the distribution to complete most of their daily tasks.
Pro Compatibility with Debian and Ubuntu software builds and repositories
Mint gains a very strong package ecosystem and software manager of Debian, including more than 30,000 packages available from the Debian repositories.
Pro Complete and stable
It's based upon Ubuntu LTS or Debian.
It depends on which one you select - Linux Mint or Linux Mint Debian Edition.
The Debian Edition is even more stable.
Pro Easy installation and configuration
Linux Mint uses the same installer as Ubuntu. It is very easy to use for beginners, and also allows more advanced users to choose their own partitions. Linux Mint's Cinnamon desktop is highly customizable and can be made to look however preferred.
Pro Provides LTS (long term support) versions
Long Term Support versions are versions of software that are continuously updated for an extended period of time, even after newer versions are launched. LTS versions will typically get feature additions and enhancements for an extended period of time, then security updates up until its End of Life. An LTS release should typically be considered good for at least 5 years.
Pro Good community support
There are several different ways to get support for this distribution, including the forums, their IRC channel, or their github repositories if you think their software isn't behaving as it should.
Pro Dedicated upgrade process
The Linux Mint team is very dedicated to upgrading and improving Mint, to the point where the releases are fairly predictable. They are also dedicated to their users, meaning that they are responsive to critiques, suggestions, etc.
Pro The OS is great for both beginners and advanced users
The OS has different update settings for different users and has easy manual within the OS.
Pro Supports proprietary software
Linux Mint does maintain a free software environment, however, it does offer full support to proprietary software (Chrome, Skype, Teamviewer).
Pro Not from a big company
Linux Mint is not Canonical, while based upon Ubuntu.
Pro Popular
Linux Mint is currently the most hit page on DistroWatch. Because of its popularity, long-term support is pretty guaranteed.
Pro The easiest option ever
The distro is the easiest operating system to run ever.
Pro There is a "system restore" tool to restore the OS if something breaks
This tool backs up the core OS files to an external drive with an option for full encryption.
Pro Has more desktop options
You can choose between Cinnamon, MATE and XFCE.
Pro Pretty desktop
Linux Mint has a quite pretty default desktop. Cinnamon is adopted by other distros also.
Pro Low learning curve to go from installation to advanced configuration
Mint is extremely easy to install, and with community support, easy to move onto adjusting the OS to meet your specific needs. The vast majority of instructions for undertaking configuration work and are easy to understand.
Pro Mint 20 will actively avoid the Snap landmine planted by Canonical in Ubuntu 20.04.
Pro 2016 hack listed here as a Con, was very quickly dealt with and is a non-issue over 4 years later.
Pro MATE desktop (as an option)
MATE is a classic desktop as opposed to the newer "Unity" desktop. For people who prefer the classic style this is one of only few modern distributions with still active MATE desktop development.
Cons
Con Stable release contains extremely outdated packages
If you want the newest packages, you'll have to do a minimal installation of Debian stable then upgrade to testing or you need to install testing directly.
Con No default support for unfree drivers
Debian does not official support unfree software so if you have a wifi card or anything elese that requires an unfree driver you will need to download the unofficial/non-advertised non-free iso image which contains all unfree driver packages.
Con Ridiculous package splitting
Even though it makes sense to split devel and the actual binary of an application, the splitting has become as mess in debian and its derivates: for example the nvidia driver is splitted into over 40 different packages.
Con Internal quarrels harm the project
Instead of working all together to provide the best Operating System, some maintainers are just ignorant and aggressive to new ideas or new maintainers. That led to many crises and controversy in Debian's history.
Con Systemd is everywhere
Systemd is very hard to debug by itself, and can break in very strange ways (such as not being able to mount a single partition on bootup), but the increasing number of desktops that are relying on specific functionality provided only by systemd (policy kit, dbus, etc) makes the entire system more fragile and harder to debug.
Con Outdated kernel of the live system
Since the LiveCD is based on Debian stable the kernel is old, outdated but stable.
Con Not designed for general desktop usage
By default, Debian Stable is not that great of a distro for general desktop usage, since the packages are very outdated. You'll have to spend a while configuring the system in order to make it work.
Con No choices
Debian basically doesn't give you any choices, even dpkg supports this feature with virtual packages: for example, it is very hard to use a different sound system than ALSA, like OSS4 or to use ALSA with pulse audio emulation, and the same goes for different init systems.
Con Inconsistent init systems
While Linux uses systemd, non-Linux ports use the traditional sysvinit.
Con Hard to learn
Con Breaks if you suspend/resume
Breaks when you resume the activity on the system if you use nvidia cards.
Con Buggy and non-user friendly
You need to know almost as much as Arch and deal with documentation not as good as the Arch wiki in order for Debian to work.
Con No good choices of fresh desktop environments
GNOME is quite outdated and buggy;
KDE is too old, even in Sid it is at 5.14 branch (at Jun 13 2019 Plasma 5.16 is available in many rolling/fresh distros);
XFCE behaves like crooked, visual artifacts at the taskbar and so on;
Cinnamon as far as I know works better in Linux Mint compared to (almost) any other distro;
For other desktop environments (e.g. MATE) can't say - these are too new (as projects) and possibly incomplete, thus might have many bugs.
Con Old software is not useful, but is stable
Certainly for the stable and old stable versions. But the testing version has quite up to date software.
Con The Update doesn't work sometimes
Sometimes the update failed to configure a package.
Con Outdated software centers
Many of the offered options are older versions.
Con Does not handle multiple languages well
Con The Linux Mint website once provided spyware
The website for Linux Mint was hacked in 2016 and its download links led to a modified ISO, which contained spyware.
Con Political
Clement Lefebvre, the lead developer of Linux Mint said “I don’t want any money or help coming from people who support the actions of the Israeli government.”
Con Looks ugly
The default theme and wallpaper looks outdated and bland. Luckily that is easy to change in the settings.
Con Upgrade process between version can be painful
The Linux Mint team offers a method to upgrade the OS between versions but they tend to recommend clean installs, which isn't always suitable for everyone. However, following the upgrade process currently is less than straightforward and is easily capable of leaving your system in a confused state.
Con System updates can lead the system to being unstable
While a new installed system is stable, after an update, there is a slight chance of something not working.
Con Mint 19 forces unwanted updates
Since version 19 Mint adopted Windows 10's policy to force the user to install unwanted updates and even if the user deselects them and marks them not to be installed, they're still being installed.
Con Cinamon environment is not beautiful and in the same time KDE environment is no longer used.
Con Nothing new
Just another fork of Ubuntu. Produces nothing that can't be found in another Debian-based distros
Con Cheap Windows substitute
Mint tries to be like Windows when it could be different and provide options.
Con Limits to the support of propriatary hardware drivers
Mint has limited support for older graphics cards beyond the generic nouveau driver, and some software (like Stremio) only works with official Nvidia drivers (for example).
Con Many proprietary (closed-source) packages
By default, Linux Mint includes almost all the proprietary packages just to improve the user experience.
Con Linux Mint tries to force people to use less powerful custom package management system
The custom package management system is slow, frustrating, and forces you to select and install one package at a time. Can't select a whole load of packages and then run the installations in one go.
Con Very boring to boring people
Con Too many kernel crashes
Linux Mint Xfce keeps crashing 5-6 times a day with no way to fix it. Endless rebooting. It is the most unstable distro.
