There are two teamliquid threads about what switches player use for SC2, it's really preference thing, so I would strongly recommend reading into this subject!
My conclusion was, that I would like brown switches more than blues, and i ordered one with brown switches recently (didnt arrive yet, so I can not really tell first hand experience).
But if the otaku you mentioned is a filco, i would rather get the filco instead of the razer, just because the filcos are built for eternity it seems.
And if you decide for the Black widow, I would recommend not getting the ultimate version, since the only diffrence is the backlighing and the USB hub afaik. not worth 50 $ more in my opinion!
