Am I the only person not having any issues with the 8bitdo Retro pads? I've been using them for my real SNES while I wait for my Nt to ship and they feel fine. Every time I think I can prove an issue, I swap to a real SNES controller (I have 4 to test with) and it acts the same. D-pad stiffness is different, sure, but I'm not seeing any issues with accidental diagonals.
I also tested out my SNES Classic controllers and the D-pad stiffness is inconsistent (down is much harder than up) but they're still reliable in terms of inputs.
