The only good Saturn pads I’ve played with have been the ones Sega made for the Saturn itself and the PS2.
The others have been third-party manufactured and NONE of them has held up as well as original Sega-manufacture pads.
I’ve got two of the “official” USB pads and will say without reservations that the D-pads and buttons don’t register as cleanly and crisply as the original Japanese pads. They’re decent pads as-is but still not as good as the originals and the PS2 versions.
Of course, the remaining stock of pads is dwindling as people break them through normal use, abuse them, or scavenge them for stick parts.
Wish Sega was still in the hardware business for controllers but nowadays their focus seems to be squeezing the last bit of money from the nostalgia crowd that loves Sonic. Don’t know what happened to that company, but they seem to have genuinely stopped caring about a lot of quality issues after the Dreamcast died…
