I’m using my leverless modified Quanba Obsidian for SF6. I really like it and it packs into a bag a lot easier than a traditional stick. My only gripe with virtually all leverless: the directions and attacks are too close together. I get that the up button is meant to be usable by both thumbs but I only ever use it with my left thumb. More often, I’ll accidentally bump it with my right thumb or bump an attack with my left index. Maybe one day I’ll make a custom faceplate but not anytime soon.
