I use Arch for 3 reasons:
1) rolling distro so you get latest software updates (good for games, bad for other reasons, see next toot)
2) Very good documentation on ArchWiki
3) AUR - no more adding PPAs or manualy building software

Pacman is also very fast package manager, better visualisation of what is being done than apt imo.

Bad stuff in next toot.
