The thumb button has 3 ways (up, down, press) the mouse wheel is lovely (if you scroll fast it releases a bearing or smt, and rolls smooth as a baby's ..) AND you get 2 other thumb buttons + it has a nice 'hold' to it.
I use that one, too. Love it. I have my "/assist focus" macro assigned to one of the thumb-buttons, and I use the thumb-"wheel" (it's not really a wheel) to rotate my characters to face moving mobs.
