I would also recommend just doing an OH since it doesn't matter what move it is as long as the game thinks the character is standing.
Ace, 6P is a high mid. In these situations, I use 6K instead and it's effective to mix 6P with 6K. If you have more advantage or as an [abare], you should try 33P.

But with these moves, it is also possible to bait and punish as they are unsafe, like Marie's 3H+K (punish with low throw).
It's a move with mid/high CRUSH frames. Some characters have incredibly good (or annoying, matter of opinions) crushing moves.
Mind you earlier,I am bad at English.
I apologize for any confusion.

I never thought effective mai 4P,thank you told me.
But I unconvinced this things :-(

by the way,I understood inappropriate "glitch" this situation.
How should I say in English in this situation?

「annoying」、「get on one’s nerves」、「bothersome」、「irritating」、「bug」、「pain the ass」

Which one is better?
Not glitches, check out muh explanation for Helena's Bokuho duck which also applies to other moves http://www.freestepdodge.com/threads/details-of-the-bokuho-stance-duck.6515/
Dont you know the rule of DOA5? if it looks like a crush, it IS a crush, which is one of the more annoying things in this game. real talk though that last one with mai, her 4p is one of those moves that pulls her hurtbox back really quickly so it can used in minus situations to avoid short range mids, Gen fu has a similar thing with his 4p+k
It's not a glitch, it's how the hitboxes and hurtboxes work. There are a lot of moves in this game that crush mids and Bass is really tall
