I don't think it's near as "exciting" as many make it sound though. These days I usually run Debian on my personal machines, before anybody thinks it's fanboy-ism or Stockholm Syndrome.
I've been using Arch on and off for a while. Back before systemd, and it had an installer.
I can't remember anything earth shattering in quite some time. Certainly no big paradigm shifts.
Packages are up to date, but they're the developer's latest release. If something is broken, wait for the fix to be released and that's about it.
I ran ~15-20 developer workstations on Arch for a couple of years. They were there before me. Being a Java shop, we managed our JDKs/IDE outside of the system packages.
