Believe me or not, but this question is actually discussed a lot.

Shadow got a lot of Chaos powers, but they won't work on Knuckles because he can feel and control Chaos as well, maybe even better than Shadow. Plus he could shut down the emeralds so Shadow would have only his speed and super human strenght. Knuckles is as strong as Sonic is fast, but Shadow is almost as fast as Sonic, so Knuckles might not be able to hit him.

In Sonic X they KINDA had a fight, but that one can't be seen as canon since Knuckles can't fly in Sonic X, so he doesn't have his full powers. Knuckles' full potential wasn't shown in the newer games. His super form was never in a modern Sonic game while Shadow got DBZ powers to please the fans. So telling who would win is practically impossible.
