Found the PSP Dpad slightly better than the PS3 Dpad as it is far less spongyI havent tried it against the PS1 and PS2 but I expect it is more responsive.
NES/SNES Master Syatem and Mega Drive D pads were excellent as long as you were going in a set direction if you wanted to do a half circle a few times well then prepare for pain and as such they were pretty poor overall for fighting games. I used to play a lot of these games on them but the PS1 had a much better D pad for this purpose and overall I believe Sony have made the best D pads or at least the ones that have given me the least blisters.
Im not to keen on the analogue nub for the PSP but the D pad I would agree is one of if not the best D pad out there (Vita excluded as I havent had a chance to play it yet)
