It's a totally different game, you can't even compare. MBAA PS2 was a shitty port and a bad game (if you compare to other MB's). MBAA to MBAACC = tons of pages of change (log), like, I didn't even want to read it all since there were so many, and I'm the kind of guy who likes to read. The game improved so much. Then from MBAACC to MBAACC 1.05 was an even bigger update then MBAA -> MBAACC... OTG relaunches came back, speed, things became looking like MB Re-Act, again tons of pages of changes. Then 1.05 to 1.07 was not a huge update like the others, but still changed lots of things (more then SFIV changes from one version to other).
Probably the game will feel the same if someone never played it, but the difference is huge. If you want to learn MB by MBAA PS2, just forget it. If you'll play an outdated version at least play the classic MBAC. If you really want to know the changes search for them like that MBAA -> MBAACC, MBAACC -> MBAACC 1.05, MBAACC 1.05 > MBAACC 1.07.
