Having a better controller can really make a difference I think, especially when it comes to fast paced button mashing. With the new controller I almost always lose my matches, with the old one I almost always win, so yes, there is a noticeable difference. The quality of the controller makes a huge difference.
Now I was wondering if there are any good controllers for PS3 that are better than the original controllers for gameplay?
Advice and experiences would be nice.
