Pro Arch Linux Wiki
Being an "easy to install version of Arch" means it is exactly easy to use the famous Arch Wiki!
Pro As slim as you want it
Based on Arch, Endevour OS keeps its core repositories slim and free of unnecessary dependencies. The distro comes with no bloatware, only the necessary packages. The repositories are nearly as full as those of Ubuntu, while they are often more up to date.

One of the best reasons to use an Arch based distro.
You can find almost every package there is in the Linux world!
Pro Stripped down to the bone
Since its stripped down, it is fast and you don't have to deal with bloatware.

Their use of themes and configuration look great!

Exactly as Arch - allows users to stay on the most up-to-date versions of the software they are using.

Rolling release means newer, up to date, mesa and kernel versions able to handle newer hardware with better performance!

Cons
Con Documentation is not good
A lot of the documentation of various functions is buried on the source code, their respective manuals, or non-existent. The documentation, the conventions, and the scattered toolchain really made searching for stuff easily missable.
Con A configuration change might end up bricking your system
Con NET installer on the way
Con Not for everyone
Con Kalu needs a little refinement
I applaud the developers to carry on the legacy of Antergos, the only niggling thing that I would appreciate is, while it's nice to see news about updates; my opinion is that once you dismiss the notifications they STAY dismissed. And just clicking on the icon brings kalu brings it to the foreground. Or have the functionality of turning off the news altogether would be well received. Good distro.
Con Same Cons that apply for Arch Linux
Since it is based on Arch, it is harder to install and can easily break.
