I wouldn't say so...the Saturn version has a slight delay during certain moves and is missing a few frames of animation (that's most visible during cross-up recovery, most casual players think there's no problem). Both of those issues were pretty much fixed in the PS2 version. So while neither version is arcade perfect, you'd be pretty safe in calling the PS2 version "gameplay perfect".
The Saturn version also had the "minimal loading" you mentioned. But I guess if that doesn't bother you, than the other things I mentioned shouldn't really either. I don't understand the players who compare and complain about these things in the home versions...especially these later and more capable ones. I think the only players who'd find these faults to be super bad and inexcusable, and who truly need that extra frame or input millisecond are probably the ones still shoving quarters into the coin-op, or own one themselves.
So I suppose it doesn't really matter, both versions are fine for just playing (even with moderate seriousness), but for the "fault-free" Street Fighter ___, the arcade version can't be beat.
