I was always a Nintendo kid so my access to Sonic was always limited. I've got the Megadrive collection for PS3 though and the games still hold up pretty well. I remember not being a huge fan of the controls when I was younger and opinion hasn't changed all that much. Flying through the levels is fun though and they are brilliantly designed. I'm probably a little biased towards Mario but the controls were always tighter, even if it didn't have the raw speed that Sonic had.
