What is the best alternative to Tails?

Like android-x86, it has limited hardware support.

As you can see Solus is new project that build from scratch.

Maybe because it's a relatively new project still in its infancy and this may be fixed in the future, but Budgie is not very customizable. You can only change the theme and wallpaper.

Non-free hardware will not work upon install of Debian and the user will need to search out the correct non-free software to install in order to make them work. This can be difficult if one of the things not working is the WiFi connection.

Debian basically doesn't give you any choices: for example it is very hard to use a different Sound system than ALSA like OSS4, and the same goes for different init systems.

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.

Arch only holds your hand a little bit of the way. While documentation is great, you are expected to know what you're doing. The result is that when you find the solution for a problem on a forum or elsewhere, the response may be completely over your head. If you're not well-versed in Linu...

The installation process for Arch Linux is not as streamlined as it is in other distributions. You have to install the OS, Desktop Environment, Network software and configure everything by yourself.

Updating an Arch system is always a gamble. The problem could be as simple as a package having a bug causing a program to crash on start or it may be something bigger like the WiFi or Bluetooth no longer working. There is also the slight chance the system may not even boot at all after a large upda...

The desktop environment used in Xubuntu has not been update in over two years and is developed at a snail's pace.

The default XFCE UI is pretty generic and sometimes ugly unless customized to suit the user's needs and liking. Customization in XFCE is easier than on Unity, but still hard for beginners.

There is absolutely no reason to install it, since it uses the same package repositories as Ubuntu and you can transform any Ubuntu install into a Xubuntu install.

The Gnome desktop environment is a resource hog which requires hardware accelerated graphics rendering in order to run smoothly, making out of the box Ubuntu Gnome unsuitable for low end systems and older hardware. Even mildly aged hardware, you'll get far better performance out of a lighter de...

There is absolutely no reason to install it, since it uses the same package repositories as Ubuntu and you can transform any Ubuntu install into a Ubuntu GNOME install.

Some aspects are still unpolished and lack features - the Gnome design team works well, but seems to not be taking input from the outside world.

SteamOS is, first and foremost, meant to act as a gaming console - it doesn't ship with even some of the most basic applications, such as a file manager or image viewer. As a result, using SteamOS as your primary operating system would require a fair bit of work.

If you've installed Arch you're probably fine, but for those used to simple installs like (Ubuntu to name just one) you should prepare some patience, determination, and painkillers. Good news is, it's getting better (it's very young).

Using puppy makes you feel like you just jumped 20 years into the past. Being that the purpose of Puppy Linux is to run or really low resource machines the software used is often on the older side, which is precisely why it has a 20 year old look.

Being a low resource distro there is zero built in compositing for the JWM window manager. Though one can be added through a bit of work.

You can barely find any precompiled packages for Puppy.

Documentation is scarce, NTFS partitions aren't automatically mounted, etc.

While you can easily get the latest VLC thanks to Void being a rolling distro, video performance is abysmal, at least for those with AMD cards.

The installer, cnchi breaks all the time. It's very buggy.

Small issue, but would be nice to see package popularity in Antergos repos, just like it is visible for AUR. packages. Antergos with AUR gives access practically to all possible packages, so popularity could help in this sea of packages.

Rolling release is quite pain sometimes. You might face some problem with a bugged application since you always get the latest version. This problem is a little bit solved by Manjaro distro where applications are tested but updates are slower than usual.

The Gentoo package management system allows you to configure what compilation flags packages should support - i.e. specific processor flag support (SSE, SSE2, etc.), -O1, -O2, -O3 optimization, etc. If you accept one of the default flags, Gentoo downloads binaries from the server. However, if you...

And if you have to update the kernel or some heavy software like Chromium it can takes hours if not more on weaker hardware.

You have to read a lot of instructions to start, even if you are familiar with Linux.

The community is fairly small, and there is no indication on the forums regarding when a issues will be solved.

All free editions only offer Windows XP, 2000, and 7 and Gnome 2. You have to pay $9-10 in order to get Unity (Ubuntu) and Mac OS X themes.

As of March 2016, RemixOS for computers is still in beta, meaning that some things might not work.

Google play is the biggest go to for mainstream android apps, so it can be quite disagreeable not to have it out of the box.

Many people seem to have problems loading React OS with nvidia cards. This may be due to maxwell driver issues.

Uses the RPM packaging system with APT, rather than the more popular DEB packages.

Unlike Debian, Devuan offers no unfree install media so if your system needs unfree drivers(eg a laptop or a tablet) its nearly impossible to install devuan on it.
