I recently purchased a Unicomp, and I have to say that BS is my preferred switch type (comparing to Browns, Blues, Clears), especially for typing.
Personally, I remember when first using BS, that I had to exert more force, but as with most switches, I got used to this pretty quickly.
Perhaps the only down side to this is that whenever my wife is at home, she does prefer that I switch over to any other board, as the sound really travels far.
Something about the crisp snap, combined with the needed force... I feel like I type with more assertiveness, and that my typing rhythm is cleaner. Maybe I'm just imagining things, but hey, it gets me through papers.
On the other hand, I did play FPS briefly with BS, and I have to say that I much preferred using brown/clears/even membrane. Somehow I felt that the snap that I like so much for typing, gets in the way of less consistent and less predictable key pressing in gaming.
