Same for Q.
Until you have seen Kuroda playing Q, you do not know the power of Q.
Youtube is banned from the office so I can't find a vid for you, but youtube for "Kuroda Q" or somesuch, and you will know the power of the stomp taunt. You will not believe the shit he does with Q, it's mindblowing really. He is ranked S in Japan which is a godlike rank that almost no one has, and still he only uses Q.
FYI Q's moves are actually pretty good too, dash fish is 100% safe on block, fist slaps (qcb+P) are too, his command grab is great, SA2 combo's from damn near everything including his command grab in the corner, etc. And of course, he has the best move in the whole game: his taunt, which gives him 33% more life, up to three times per match. That's twice as much life with just three taunts per match which are pretty easy to do safely as well, and even if you can't do the safely, who cares if you get hit out of third taunt, worst case scenario your opponent wastes a super meter to remove the health you just got if even that, so you lose nothing on the whole tradeoff while the other guy wastes a super meter.
