Also tried Gentoo a couple of times over past few weeks.
I like how I'm not limited by package versions for software and also very minimal.
Just followed the handbook and had a minimal openbox desktop setup.
I heard Gentoo's documentation was great, their handbook and Desktop documentation definitely showed it.
Not sure if I will use it again, although I have been benchmarking Ubuntu, OpenSUSE, Debian, Windows using the Unigine Heaven Benchmark, so I wouldn't mind seeing how my Gentoo openbox would compare to them. So far Debian is in the lead. link - [link]
