Arch is nice, I noticed slightly higher fps in a few games after switching. Not sure how much overhead there is on it, but I use AwesomeWM which I launch from the commandline since I don’t have it run at startup, and I must say I do like the interface for launching programs, I can either do the commandline name or the name of the program will often be fuzzy find away in the launch bar…

If only windows had some kind of menu where you could find programs to launch (and not search the web), and not cram adds down your throat.
