nice. what i like most about the snes controller is that its light and the lightness feels just right on my hands. but beside that, i find that the playstation controllers better. its not as light as snes controller but the buttons feel very comfortable when pressing it.
late last year as i played old snes games, and after a few hours playing, my fingers sore a little bit. while i can play for long hours after hours with the psone and ps2 controllers and my fingers still doesn't sore at all. same with ps3 controllers but i think the l2 and r2 buttons are better on the psone and ps2 than on the ps3. but they still feel very comfortable. except the newer ps3 controllers feel a little cheap compare to the old ps3 controllers.
i remember playing final fantasy vii using psone and later ps2 and ps3 controllers for long hours as long as 7 to 8 hours straight with restroom breaks in between and my hands still feel fine. same with spyro the dragon that i played recently and my hand still feels fine after playing the game for many hours using the ps3 controller. while the snes controllers, after playing it for a few hours my fingers started to sore.
