For me, it depends on the distance Talim's away from the opponent, and what I'm punishing. 22B is kinda slow, so I use 33A when I'm close, 22B for big moves. At a distance, I mix it up 22B with 11B, 22B for RO, wall combos, and damage, 11B to tech lows(Mitsu's 1A, the low sweep AT of Ivy's) and for mixup potential. 11B also has more range than 22B. I'd use 11B~6 AS A+B, but that doesn't hit everyone, and for some reason my timing's been off for AS A+B transitions.
My other main step punish is WC K and WC throw. I also use WC B:B, but that depends on whether I'm playing really safe or not. I've also been trying to use WC~AS A+B for moves who move past me(i.e. NM's 66B(?) to GS and Yoshi's 66B), but I gotten accustomed to it yet, and mainly use it for long range baiting.
