Ranked in these QuestionsQuestion Ranking
Pro Privacy focused
Pro Has TOR built-in
Use the Internet anonymously and circumvent censorship; all connections to the Internet are forced to go through the Tor network.
Pro Flatpak support
Having Flatpak support adds a nice graphical app store to the OS. You can find most software you might need in there.
Pro AUR enabled by default
The Arch Users Repository is already enabled. Really helps with finding some proprietary software.
Pro Arch Customization without the hassle
You can choose from 15 different desktop environments. Choose from a list of software to install that lets you pick web browsers, Spotify, what kind of office suite, etc. Not as robust in terms of choosing what you install compared to Arch, but more than enough for newcomers and those just looking to get things done. Nice midweight OS.
Pro Runs Android apps
Reborn OS has a program that allows you to install and run Android apps on your desktop. Great for app developers or those who might be addicted to a certain app.
Con Not for daily use
Tails is a privacy focused Linux distro. The updates that you will receive are only for improving privacy and not for improving user experience.
Con Saved states are not present for security
For security reasons, saved states are not supported in Tails. Files can be stored in a separate, persistent volume which must be accessed with a root password. Personal settings (e.g. -- keyboard layout, window settings, etc.) are not saved persistently across reboots. This can be a hindrance for anyone not using English as their language, or not using a QWERTY keyboard layout.
Con You can't install it to a hard drive
Con Slow internet
Tails uses the TOR network and as a result the internet on your computer will be very slow.
Con Can be a little buggy sometimes
Although not outright system crashes or freezes, but programs not working correctly after an update is quite common. Some desktop environments can be temperamental. Examples: running Deepin DE at first and the zoom for the display is 150%. You can fix this by going to settings and setting the desktop to 100%, but then something else might happen, e.g. you lose icons on the dock. Minor headaches and some are easily fixable. Certainly not a deal breaker.
