I've seen some Gentoo Bashing going on into bsdforums.org
As often, it came from people too lazy to really discover something new and its pros... Well... Honestly, I find eveything in Gentoo is much more straight forward. The customization level is higher than anywhere else, and I generaly find Linux more user friendly than BSD's... Anyway, i must admit I only used NetBSD so far...
Of course, as far as I know, I'm not yet omniscient, and therefore, all this is only personal taste. Anyway, BSD advocates are often very narrow-minded, what's more, they tend to see GNU/Linux as 'too much user-friendly'... The BSDLeet way
They spit at nOObs, and the F in their RTFM really means Fucking... Anyway, those systems really feel mature and damn stable, and contrary to what some ppl say, their port tree is not so outdated...
So, why using GNU/Linux (Gentoo of course) and not BSD? Well... to me, it's because I love the whole idea of the GNU Project. But still... Personal opinions...
PS : they do have reverse dependancies though

PS²: anyone could teach me an alternative to the 'anyway' word?
