arch resides in a special place in my heart. as long as what they do is reasonable, I give my support.
I'm a big Arch fan but moved to Fedora because the overhead of managing updates in a rolling release got to be too much, and Fedora is very similar to Arch in conventions it follows, so most of my knowledge transferred over seamlessly (other than package manager of course). Moving to Mac OS though seems like it would render most of your knowledge/experience useless. I got stuck on a macbook for a short-term contract and found it maddening and confining in so many ways
Also, I guess it really doesn't matter in the end because all my development happens in Debian containers anyway. Hell... I could even use a Surface Pro and it would only slightly annoy me lol - the absolute beauty of containers!
Fedora? Maybe it was because of rpm prerequisite hell vs apt-get/pacman's auto install of whatever is needed, but moved away from RedHat after around 5.0/6... but then again, I'm sure that's all changed too. Maybe I'm just old :)
