Manjaro allows the user to access of the Arch User Repository, a very large user-maintained repository of packages for Arch Linux and derivatives.
Specs
Ranked in these QuestionsQuestion Ranking
Pros
Pro Arch User Repository access
Manjaro allows the user to access of the Arch User Repository, a very large user-maintained repository of packages for Arch Linux and derivatives.
Pro Support for multiple kernels
Manjaro has built-in support for multiple kernels as well as a way to easily install them. Using LTS kernel makes this distro stable and less buggy.
Pro Based on Arch and user friendly
Manjaro is an Arch-based distribution with all the benefits of the Arch ecosystem and community but with the added benefit of being much more user-friendly than Arch.The overall features it provides is hard to beat. Arguably be the best desktop distro with lts kernel. Consumes very less ram.
Pro Excellent graphical package manager (Pamac)
Features include: providing notifications of available updates; mirror management; Snap support, Flatpak support and AUR support (with the option to suppress unnecessary confirmations during the install process); update settings (frequency, whether to check for updates from the AUR, packages to ignore updates for); and a history of packages installed, updated, or removed (from the official repositories - AUR packages are not currently tracked).
Pro Improved stability due to a longer testing period for new packages
Packages from Arch's repositories are tested (about two weeks) longer for stability and compatibility issues. Patches are applied, when necessary, before being made available in the stable repositories.
Pro Friendly community
If you ask questions of users in their forums or on other platforms, they are willing to help you. Also according to the developers, they are open to new ideas in order to make the distro better.
Pro Very good looking desktops
All desktops look good by default.
Pro Stable and consistently up to date
Manjaro receives regular updates, but more importantly these updates are stable. The updates are rolled out, which means you can easily update the software without needing to re-install.
Pro Installation is a breeze
Calamares installer and MHWD is the reason why this distribution is good for desktop user- friendliness! Audio codecs, latest packages,latest kernel and easy upgrade to the latest build makes it the best choice for new users.
Pro Good documentation and forum
The Manjaro community is very helpful, and there are lots of tutorials.

Pro A rolling-release distribution
Manjaro uses a rolling release method for all updates, so once a system is installed, as long as the user regularly updates there is no need to re-install.
Pro All major desktops and even less common ones like Budgie, Lumina, LXQT, Deepin, Enlightenment, etc. can be directly installed from official repositories
Also available as independent variants.

Pro Uses low memory
By using Xfce or Plasma (or LXDE, Fluxbox, supported by community) as default desktop environments, Manjaro is able to have a low memory footprint.
Pro Manjaro provides its own distribution-specific tools such as the Manjaro Hardware Detection (mhwd) utility, and the Manjaro Settings Manager (msm)
Run automatically during the installation process, it allows for Manjaro to work fully on your system 'straight out of the box', without the need to manually identify and install the necessary drivers or to manually edit the appropriate configuration files. Also usable via the terminal after installation, the features of the mhwd command include:
- The choice of free (i.e. open-source) or non-free (i.e. proprietary) drivers
- Identification and listing (general or detailed) of your system's hardware
- Identification and listing (general or detailed) of installed drivers
- Listing of available drivers for installation (free and proprietary)
- Support of hybrid graphics cards (e.g. Nvidia Optimus)
- Easy removal and installation of drivers (selected automatically, or you can identify and choose your own)
Pro Different editions to select from + Manjaro community
You can choose between different Manjaro editions which have their own change in features, and there is also Manjaro community editions where the community can make their own changes.
Pro Steam installed by default
Pro Deepin desktop environment is worthy attraction
Pro Full access to AUR
Pro an Nvidia ISO version with drivers pre-installed.
Works perfectly.
Pro Polished UI
The UI of Mac OS is rather unrivaled. The smooth, responsive, and cohesive UI makes the system quite joyous to use.
Pro Easy access to lots of great dev tools
There's a large selection of great development tools available for OSX. The operating system itself comes bundled with a powerful terminal emulator, called Terminal. Additionally, Apple provides tools, like Xcode, an IDE that contains a comprehensive collection of tools for developing OSX and iOS software, for free.
Pro Based on Unix
macOS being a UNIX certified system means that you can install a lot more stuff with a lot fewer headaches than if you were on Windows.
Pro Powerful terminal
It's very similar to a Linux terminal.
Pro Best support for Objective-C
Pro More commercial software and gaming support compared to other Unix systems
Adobe CC, MS Office, Steam games.
Pro Has many special tools for developers
Has support for multiple IDEs.
Pro Lots of open-source software available
Because it's Unix under the fancy GUI, most open source ports easily to it.
Pro Ideal setup, out of the box
Next to no custom configuration is necessary.
Pro Great Git GUI tools
Tower, Kaleidoscope, SourceTree.
Pro Has software that only runs on Mac
For example, Sketch.
Pro Streamlined workflow between devices
Because this is an Apple product, there is a streamlined workflow between your computer and all mobile devices. For example, if you type an a Pages document, once you save, you can open the updated document just moments later on your iPad, and vice versa. The same goes for iMessage, (yes, you can text people with your phone number from your computer. Actually, you can text other people with apple devices with just your Apple ID, with or without a phone number, for free!) Numbers, Notes, Reminders, Contacts, and just about any other Apple workflow application.
Pro Great modifier key layout
Pro Using VMware you can also run Windows 10 on the Mac
This is useful for testing and some development tools that are Windows-only (XML Spy, MapForce).
Pro You need it to compile macOS or iOS apps
Cons
Con Slightly bloated
Con Can still be unstable
Here are the details of it.
Con Bad dependencies
This is similar to the mac0S experience in that you're not allowed to remove plank.
Con All the small community editions are gone
No architect edition anymore, no edition with a tiny stacking WM like openbox or fluxbox that could be used as install base.
Con No real installer
It just boots the livecd and copies the livecd to the disk which gives you no choices in software selection.
Con Installation is extremely buggy
There's no easy way to switch from local keyboard layout if non-Latin installer language is selected.
Con Very slow development for 32-bit hardwares
ArchLinux-32 community maintain their forums every day. They upload new ISO's every month. But Manjaro-32 community upload new ISO's in every 6 month. And provide only a DE-mate.
Con Weekly manual updates
Since it is rolling release, it needs updates nearly every week, which (though are checked for automatically) must be manually downloaded, confirmed and installed. That may annoy or scare off many new users.
Con The Manjaro unstable repository is slow to sync with the Arch stable repository
The Manjaro unstable repository syncs with the Arch stable repository and if any package has moved, it gets moved to stable.
Manjaro gets package updates a bit than Arch.
Con Imcompatible with Arch User Repository and archlinuxcn
Because Manjaro packages are not synced with Arch, using AUR or archlinuxcn could break dependencies.
Con You can't change the default theme in certain applications
Although it is possible to change the default dark theme, this has no effect on Firefox, which appears to have the dark theme "hard coded". Hardened Linux pros may find a way to change this, but for the rest, it renders an otherwise nice distro a no-go.
Con Deepin desktop environment is not a worthy attraction, there is a problem with changing Multi language layout
Con Nothing new
There is nothing new in Manjaro compared to any other Arch based distribution.
Con Redundant
It's just Arch Linux with an easier installer so there is no reason to use it.
Con Same cons that apply to Arch Linux
Since it is based on Arch Linux.
Con It's Archbuntu
Con Black screen after boot, no login possibility
Con No gfvs pre-installed
So no Trash (and possibly smartphone file system access via USB) support.
Con Bad way of handling dependencies
Manjaro is based on Arch Linux. Arch Linux and its derivatives have a bad way of handling dependencies. To handle dependencies, it installs a whole another program which contains the required dependencies.
Con Expensive
OSX is tied Apple hardware and Apple hardware tends to be expensive for what it gives.
Con Limited hardware
Usually, the hardware that can run this can't be upgraded.

Con Most software is closed source
For people who like to use open source tools for their development work, this may be a problem. There's plenty of advantages to open source software, one of which is the ability to tinker with and customize the tools themselves that you are using. Although there's plenty of FOSS tools available for Mac, especially through Homebrew, the number of packages available is much lower than the number of packages available for any Linux distribution.
Con Closed source
Mac OS is closed source itself, which means that it is developed more slowly and has more problems.

Con No native package management
A comparison of package managers available for OSX can be found here.
Con Poor application support
Fewer apps run on Mac OS than on Windows or Linux.
Con Bash version is obsolete
macOS comes with an obsolete version of Bash, due to licensing issues.
Con Vendor-Lock-in
You are now forced to use the Apple services.
Con Silly modifier keys layout
The Command key is strange, Alt is where Super should be.
Con Poor X11 integration
The most open source software does work but is very poorly integrated due apples ancient version of the X-server.

Con Very few options for running hosted, on the cloud
Con Too little customization options
Con Touchbar on Macbook Pro's
Con Not very user-friendly
