I mainly dislike not all elements have the same quality art/animation (Elena hands ug). Mark of the Wolves looks so much more consistent and is an equally technical gem of a game, but I actually prefer how the Alpha games look anyway, even though they didn't push animation to that high level.
MOTW gets overlooked a LOT in these talks, but I think it deserves attention as well. I preferred its Just Defend system over SF3's parries, not just because it was more forgiving but because it also felt more natural to do. That and, IIRC anyway, you either couldn't do them in the air in MOTW or if you did, they'd push you back forcing some type of reset back to neutral.
Art/animation-wise it's amazing, too, and it has a great roster and arguably did more with its returning lead and some of its new characters than SF3 did. I mean they managed to make Terry look and feel like Terry while still making him fresh and giving him a makeover. Rock being Geese's son and being of age enough to compete was big story-wise for the franchise moving things forward in the timeline, something SF is still afraid to really commit to.
For 2D background art tho I think it's between SF3: 2I, RB FF Special and Orochi-saga KOF games for best in the genre. So much craftsmanship in that background artwork.
Most overrated FG of all time.
I do think 3S is kind of overrated, too. By how much I can't say, but it's like there are people who will always complain about balance in SFV acting like 3S doesn't have a broken tier list. Maybe it's because most of those people only played with top-tier anyway. Characters like Remy don't even have a real cross-up (and the only he sort of has is either a jump attack with a 1% chance of working, or timed meaty booms to someone in the corner and even that isn't reliable).
It gets a lot of hype from EVO Moment #37 but that's not even the most cool stuff I've seen from competitive 3S TBH. I can respect it, though. Sometimes it feels like the endless praise 3S gets does a disservice to other great fighters from the era including some that do some things better than 3S, and there are quite a few of them. All that said tho, even with its issues I still love the game and it's probably the one fighter I'm most acclimated with skill-wise, tho I've been wanting to learn other fighters more seriously too.
