Sorry, but no. 44P is stupid. The stun is 16 frames for a 15 frame mid punch. 6P is only 13 frames and gives a 2 frame stun. And has two possible follow-ups. What do we get in return for this discrepancy? 44P is -8 on block (9P is -9) does 2 more damage. 2 measly points of damage.
44P's only use is as a spacing tool. It's really hard to describe and to pull off, but I don't consider it a good pressure tool at all.
Anyway, PP4PK can be used if people like to retaliate from your jab strings as a pressure tool. Condition PP4P, then toss that fucker out. Still, way way way way way less useful than the old one.
WR4K9P is used to make people whiff mid P holds expecting the hella-telegraphed WR4KP
4H+K9P is just dumb as fuck. I don't even...
H+KKP can be used if people just like to duck the whole string, but otherwise it has no discernible use I've found.
WR H+K covers a surprising amount of distance quickly, and with good spacing baits, can be used to snub SSing and even as a unique whiff punish then sends your opponent flying into shit very, very far away.
33T is godly on those low hold spammers.
44P+K actually crushes mids in certain frames, and is his best post-CB move (duh) most of the time.
9K might as well be a new move since it behave so differently. It's much better now.
