I am actually a fan of double tap to dash too - but when playing Streets of Rage 4 with a buddy of mine last weekend he said he doesn't really use the blitz attacks in the series much as he finds the double tap forward and attack required to pull them off cumbersome. They're like my bread and butter moves in the game so this was a revelation for me
I have my own control bugbears though - I hate anything being mapped to clicky sticks (L3 and R3 as consoles likes to call them, as if they're real buttons) as I find them awkward to use, and I've seen a few games lately start using R1 for attacking which just seems crazy to me. For any action I use regularly I'd rather use a face button as hitting buttons with my thumb is more comfortable. I don't mind triggers because normally stuff mapped to those is something you hold down, rather than tap repeatedly.
