I really cant decide. I feel as if I can get things down easier of the Dpad, but its not as consistent. If anyone has any advice as for which is better in the long run, it would be welcome.

I prefer the circle thumb pad because the D pad is just a little too low for my thumb..

the D-pad directions are small so its hard to do combinations on it

I prefer the C-pad

The choice seems to be a delicate balance between comfort and accuracy. Usually if I'm playing offline, I use the C-Pad because it's more comfortable. If I'm playing online and winning means a bit more to me, I'll sacrifice the comfort for the more accurate D-Pad so I don't fuss up any of my combos.

C Pad for sure. It's a lot more accurate.

The D-Pad, because I can't dash as much using the Circle Pad, and tend to mess up on it. xD;

It depends on you individual preferences. You could use them both like d for easy combos and dashes and circle for more complex.

You have to be holding you're 3DS right. If you hold it right, you can use both at one time.

I prefer the circle pad. Not just for SSF4, for any game. It just feels so much more comfortable.

On the console, I use the analog stick. But on the 3DS I use the D-pad, the C-pad is too sensitive for me, dashing makes me jump lol
