Specs
Ranked in these QuestionsQuestion Ranking
Pros
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 Easy to use with an USB key
Pro Easy to install
ArchLinux is rather hard to install using command line. Antergos's advantage is the easy installation using a GUI.
So instead of manual installation of software you can just download Antergos which does things for you automatically.
Pro Rolling release model make it easy to keep apps on updated versions
Antergos is a rolling release distribution (as it's based on Arch Linux). Your entire system, from the base OS components to the applications that you install, will receive updates as they are released upstream—with only a minimal delay to ensure stability.
Pro Offers choice of desktop environment on installation
Ability to choose your preferred desktop environment on installation.
Pro It comes with every essential utility pre-installed
Pro Arch User Repository access
It can visit AUR to build packages.
Pro Offers minimal ISO download
Pro Surprisingly stable Linux desktop
From popular distros of rolling and standard releases, compared to Debian (stable) and Arch, Antergos stability rocks. Debian is stable, however, it's with old packages and Arch. The only thing that broke it, so far, was compiz-manjaro (C++ 0.9 branch) from AUR, but compiz in Antergos repositories is 0.8 and it is working flawlessly.
Pro First Linux desktop that makes Windows look bad
Antergos has very nice default themes (KDE/Plasma and Gnome/GTK), which combined with Compiz 0.8, makes Windows looks sad. Antergos can even compete with Windows in regards to stability.
Pro Excellent graphical package manager (Pamac)
Features include: providing notifications of available updates; mirror management; 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 Extremely fast
Everything runs at the speed of light. Antergos is super responsive and programs/apps runs effortlessly.
Cons
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 You can't install it to a hard drive
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 Only GNOME desktop environment
Con Slow internet
Tails uses the TOR network and as a result the internet on your computer will be very slow.
Con Antergos project has been discontinued (May 2019)
Con Package popularity is not visible in Antergos repositories
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.
Con The installer breaks often
The installer, cnchi breaks all the time. It's very buggy.
Con Rolling release problems
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.
