Compared to Tekken (I'm also a Tekken player with SC on the side), SCV does seem more masher friendly, and matchups are much easier to learn mostly because there's fewer characters and movelists are short. Just an example but seems like in Tekken, you'd better think hard before you throw out that low (ANY low) since WS punishes are stupid fast and you can get launched hard or low parried. In SC, not all characters can even properly punish slower lows from long weapons with WR stuff (and there is no low parry like in TK), so many depend on buffered commands like Asta bullrush or Natsu 66B to punish with enough range and damage to make offenders hesitate.
Also in SC, you got characters like Pyrrah who can win high level matches with nothing but basics, like backstep and BB/AA. They call it her "pokes" but honestly they do so much damage and are super safe and fast that you can literally just spam it with no fear of punishment unless you completely whiff. Seriously, that's all she needs (and maybe the occasional stab punisher). To me, that almost seems like, say, Kaz with a mid hitting 1,1 and a tracking high 1,2 or something and being able to win using just that shit alone combined with BDC and WD lol.
SC does seem more character specific when it comes to certain strats, since everyone can have different speeds on basic attacks like BB/AA. BB/AA in SC are go-to pokes like jabs in Tekken, but all jabs in Tekken are i10 so that's very different. So depending on who you play, your AA might not punish something that say... Natsu's AA will. And from what I've played in V, I seem to not even be bothered by low/mid mixup game as much as in Tekken. It's the run counters that I tend to focus on, which is something Tekken does not have. You literally can't even move in SC without getting CH to death.
Oh and you cannot read throws in this game most the time. It's a total guessing game, A or B throws have the same animation unlike in TK.
So yea, those are just some of the things I had to adjust to moving back and forth from TK to SC.
