You really shouldn't speak for others. It's all personal preference. I love Black switches for typing and gaming. It techincally wasn't the first I tried, browns were first, but that was a friend's board. After him letting me use it for two days I bought a Filco with blacks and love it.
Most enlightened people will agree blacks are the worst of the three common cherry switches, thus, if a person is buying a cherry based keyboard without trying any, browns or blues are a better choice than blacks and will make a user happy a larger portion of the time. Can't really argue that one.
There's a lot of blacks in "gaming" keyboards because of the misconception that they are better for games, which is simply untrue. Add in marketing, and you have people that are buying crappy cherry blacks because they have drunk the Kool-aid.
Yes, I agree it's a personal preference, and a small minority will actually like blacks better than the other switches, once having tried them all.
However, blacks are still a bad choice most of the time, especially not having tried other switches, and I recommend against them in this scenario.
