I’m far from an expert on fighting games but I have a couple sticks.
One is the Agetec official stick for the Dreamcast. I had to get it because I found it just about impossible to play Marvel vs Capcom 2 with the stock DC controller.
The other is the Mad Catz Super Street Fighter IV Tournament stick for PS3, with the lenticular image of Chun Li on it. Fortunately Street Fighter V is backward compatible with it so I used it for that game too. Works much better than the typical PS D-pad, which I always found to be terrible for fighting games (all the way back to Battle Arena Toshinden on PS1)
