I thought the six button Duo-RX pad is really great, and I have no problem with it for Street Fighter II'. I also have a Avenue Pad 6 (though it's controller port gives me annoying problems), I actually prefer the RX pad more for fighting games. For non-fighting games or non-six button games, I stick with the good old PCE or Turbo Duo pads, they are some of my favorite pads in gaming . Comfortable, slick, and convient. Similar to the NES pads (which I also love, but that's definitely on debate with other people), but with rounded corners that feel nicer on the hands.
I love the Turbo pads and the SNES pads are also great. I hate Genesis pads, although the 6-button pad is better.
This is of course the exact opposite of the opinions(and therefore truth) of every U.S. game mag.
I also don't like joysticks in most cases since they're less accurate. The way always explain it to people is: If you played with a 100 foot joystick, you'd have to run around a huge circle just to move the damn thing. It the same with any joystick, the longer it is, the greater the distance you have to push it to respond. Where as a pad is flat and you're essentially(or literally in the PSX's case) just pushing a button everytime you use the D-pad.
As for the pads, I love both the D-pad and each button on
Turbo/PCE pads.
I don't like the
SNES pad as much, because of the harder plastic and the barrier of the cross cut in the actual controller. The buttons are nice, but again, I prefer the softer plastic on a Duo pad and I find that the button's springs in SNES controller don't respond as well to the way I play. And nothing beats the rubber RUN & SELECT buttons of a Duo pad.
Now, the big ugly manta ray/boomerang:
Genesis pads. I don't mind the way they look, but a team of scientists spent years in research to custom make pads to not sit well in my personal hands. I won't use the metaphor I normally do for the pad, since I don't want this post removed, but the pad is big and sloppy and doesn't respond well. The six button pad is better in everyway and I enjoy using it(especially on SMS), but I still prefer the SNES and Duo pads more.
I don't hate the RX/PCFX pad, but it doesn't do diagonals well for me on too many non-fighting games, so it doesn'tget used anymore. As for the PCFX pad, -I don't really have much of a choice do I?
