Who would win in a fight?

Shadow or Silver? Don't say it because you like them better, say it because they would actually win in a fight and tell me why. No biaesd people (specificly, Silver fanboy/girls) and if you think thatv Silver would win, tell me why. If someone says Shadow and doesn't tell me why, then i'm gonna tell them to tell me why they think he would win. We all know Shadow would win, but I still need you to say why you think they'd win.
