Antergos is a great combination of features:
- easy and fast to install
- very up-to-date packages!
- a large amount of packages
- includes directly some very useful proprietary packages
- great community!
So far I haven’t seen any other distro with all of these features combined. Technically Manjaro comes quite close but comparison between these distros is not easy since they seem to have slighly different goals (technically speaking the unstable branch of Manjaro has about as up-to-date packages as Antergos).
Naturally a big part of the glory here goes to Arch, but I must say that the Antergos team and people have done a really great job!
So these are the reasons why I use Antergos.
