Nope. Like Mystic said they're just different skins. They all have exactly the same movements and abilities, but they do have different animations like Shadowunleashed said.

Oh and don't spend money on red rings. Just save them up. I've got Blaze and Tails so far just from that.

If you're connected to the internet while playing, you can get a red star ring on the second run each day when the chalenges resest. Just don't spend them unless you have to get something for a challenge that you can only get with them (e.g. Super Head Start- or whatever it's called.)
