I like my 103U variable for gaming, though the 104U would mean I can finally replace my spacebar =_=. My ring finger is weaker than my index and middle fingers so I find having A lighter helps. Also I don't put my mouse on the side of the keyboard so the numpad geting in the way is a moot point.
However, favourite Topre board is definately my Short Throw. Not as good for long typing, but my god is it good for games. Love it for RTS and I kid you not, when playing rhythm games on my computer with it like stepmania, I beat most of my high scores (to be far, by only a small amount) almost instantly after switching.
