Sonic is stronger than Shadow In my opinion. You see Sonic fighting more difficult things than Shadow does. Yeah maybe Shadow hasn't had a chance to fight things drastically bigger in size but Sonic has because he's had more games.

Also Sonic doesn't need inhibitor rings to control his powers. He matches to Shadow without having rocket shoes or using a chaos emerald.

I agree Shadow's a cool character and is even my favourite character alongside Sonic (I like them both equally) but I think Sonic is stronger physically and mentally

Edit (12 January) - Shadow may have held back on Sonic but I don't think Sonic had that much trouble beating Shadow when he held back which leads me to think Sonic wasn't trying much either. Shadow held back on the fight because he wanted it to be a fair fight and knew it was unfair to use his doom powers because they're were more black dooms powers than his if I'm correct.

Sonic has a form stonger than any other form from every character (hyper sonic) so realistically he should be the strongest character and also Shadow's has never canonically beaten Sonic. Just because Shadow held back doesn't mean he could 'easily' beat Sonic.

Another thing we haven't seen Shadow enough times without his inhibitor rings off but they seem to help him control his powers not as much to contain it and Sonic can control his powers without any assistance as I said earlier.
