It looks like that arch is there too, if you look for the same characteristics in a binary distribution. Not sure about their patching level though.
And the number of stupidities to fix is rather low nowadays. A little higher that for a binary distribution due to the somewhat extreme configurability, but not bad. Running gentoo is nowhere near as "l33t" as it was some years ago.
