Specs
Ranked in these QuestionsQuestion Ranking
Pros
Pro Protects your freedom, certified free by the FSF
Pro Option to use OpenRC or Systemd
Parabola has an OpenRC edition and a Systemd edition, so users can choose which init system they want.
Pro All the benefits of Arch Linux, only 100% certified free software
Pro Very Secure
Pro Has its own repos
Parabola has its own repos (which are almost as large as Arch Linux) and the IceCat browser is included.
Pro Can be migrated from Arch Linux without a CD/USB
Pro Based on Arch Linux
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 AUR enabled by default
The Arch Users Repository is already enabled. Really helps with finding some proprietary software.
Pro Very stable
Pro Great community!
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.
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.
Cons
Con Won't work out-of-the-box on the most PC's
Almost all PCs need non-free drivers but Parabola has none to offer.
Con Not compatible with AUR
Unlike other Arch-based distros, this free distro doesn't support AUR.
Con Same cons that apply to Arch Linux
Con Small repositories
Since Parabola is a completely free distro, there is no non-free software available and the community repositories are small compared to the AUR.
Con Incompetent developers
They only care about removing "non-free" software, rather than making a properly working OS.
Con Serves no purpose
It's just Arch without non-free software and is basically a niche OS with few users.
Con Not really free
People have to pay hundreds to maintain this distro.
Con AUR enabled by default
this is a security risk since AUR packages are maintained by users rather than a single company and anyone can insert malicious code into the AUR packages
Con Redundant
it is just Arch Linux with an easier installer and doesn't provide any functionality that neither Manjaro nor Arch doesn't already have.
Con Uses systemd
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.
