Haven't touched H-Miyako at all. C-Miyako feels more or less like MBAC Miyako? Keep in mind that my memories of MBAC Miyako are very fuzzy so I can't really say something like "oh it's a bit slower/faster now" or whatever, but overall she feels very similar.
F-Miyako cliffs notes version:
5A - more or less the same as always
2A - more or less the same as always
5B - kick with decent range for Miyako
2B - new low kick move (same as H-Miyako IIRC), pretty good but range isn't as good as 5B
5C - more or less the same as always? Can BE.
2C - more or less the same as always
6C - two handed shove punch, cancellable and JCable
all jumping attacks are the same for the most part, maybe some FRAMES differences that I don't know about
Throw is still the same.
236A/B/C is her flying dragon kick move. 236A goes up more, 236B is more vertical, 236C is an EX, etc. etc. Can chain to 421.
214A/B, she steps forward and does her old 214 punch. Can be charged now. 214C is her old 214C.
623AA/BB, 623AA is pretty much her old 623 except you can jump cancel it on either hit, 623BB is more horizontal. 623C is pretty much her normal 623C. All versions can be done in the air.
22A/B are her stomps as usual. 22C is the flip into stomp, still hits low.
421A/B are the elbow drops. JCable, floor bounce on air hit. I forget if 421C changes in appearance or anything, it's more or less the same kind of move though. You pretty much only do this after 236.
AD/AAD are pretty much the same?
Didn't check LA.
