^ You are correct.
Also the Saturn version has some issues that keep it from arcade perfect. Mainly larger sprites than the CPS2 game (the Dreamcast had smaller sprites than the CPS2 game, the PSX was closest but suffered from loading and cut frames) and Dhalsim changes. So from a hardcore FGC perspective A3 on the Saturn was still bad. Gameplay wise the perfect non-CPS2 A3 didn't come until the PS2 Alpha Anthology version mainly because Capcom actually gave a shit this time and allowed players to even play with dip switch settings to have the 1-1 experience.
Of course for collectors or general fans, this shouldn't be an issue.
XSF and MSF both had aspect ratio issues and the former was based on a later revision that was rarely seen/played in arcades (e.g. some infinites removed). Again that is just a FGC nitpick.
Vampire Savior is pretty much better than perfect as it is the original VS (not VH2 or VS2, both terrible revisions) with returning VH characters. The trio were originally left out of the initial CPS2 VS because of hardware limitations, and with the fact that the CPS2 (like Capcom's boards in general) commit suicide unless modded, makes the Saturn the definitive version as it also has an option to use the CPS2 correct aspect ratio. Gameplay wise after the use of dip switches the PS2 collection comes through, and then the IG and Capcom Japan last gen digital ports.
Pocket Fighter wasn't played competitively and afaik, the Saturn game is identical to the CPS2 game.
MSH doesn't take advantage of either RAM cart well, and the SNK games still have loading (way better than the PSX games) with the SNK 1 Meg Cart.

Yes these are just screencaps from YouTube but even then, puts lots of other versions to shame.
