i'd say NM, he has all the tools for a grounded situation
if the opponent techs, they risked being relaunch (assuming its a tech trap situation), if not they still eat garunteed damage, if they still stay grounded you get more damage from 44BB, or you can kick them out of the ring with GS KK, if they start rolling, you have 1[A] to apply pressure, or FC B+G/A+G to pick them up (although this doesn't give you advantage anymore), or if they are close enough it's a free 2A+B and force them to get up with a charged 3B. Most his B moves hit grounded, so hitting ground targets isn't any issue for him.
