Goku of coures
actually, to be honest: Goku is an famous anime character and Shadow is an famous video game rival character. i mean, just look at them: Goku is the hero who saves the earth from evil bad guys and his biggest rival was Vegeta. as for Shadow, he is just like Vegeta! he always hates Sonic and always challenges him to an battle.
Goku is more famous than Silver the Hedgehog. Goku is a central character in the extremely popular Dragon Ball series, known worldwide for its impact on the anime and manga industry. Silver the Hedgehog, on the other hand, is a character from the Sonic the Hedgehog series, which has a strong fanbase but is not as globally recognized as Dragon Ball.

Okay… This is an absolute obvious answer. Goku. Goku guys. 1.) Goku is just so much stronger. Even in base form, Goku‘s physical strength is greater than that of Shadow in Super form 2.) Goku has several transformations and his power multipliers are far more crazy! 3.) Goku also has god Ki. {Even IF Shadow could canonically use Hyper and go into Chaos while in Hyper, the furthest Shadow might even be able to be on par with is a complete Super Saiyan Goku} 4.) A lot of things Shadow can do, technique wise, Goku can do. {Shadow can teleport and so can Goku. Shadow can use energy blast, so can Goku.} Those are reasons why Goku would win Here are some reasons why Shadow might win 1.) Shadow has the speed advantage. Yes. Shadow can move at Light speed. He is faster than Goku {But Goku has Ultra Instinct and literally can just evade any attack with it} 2.) Shadow can freeze time. {Goku did manage to break through the time barrier with Hits timeskip attack however, but I am not too knowledgeable on that area} Furthermore, Shadow can only freeze an object or being for a total of 90 seconds - [1 minute 30 seconds] All in all, Goku has an easy overwhelming advantage and is far more skilled at combat because of his martial arts and godly capabilities

Goku and Shadow would win. The facts are that Goku clearly exceeds Vegetes power limit, even when both of them are in Super Sayain 4 forms. Shadow and Sonic may be evenly matched but if Goku finished off Vegeta, he could step in and finish off Sonic.
Goku is because he has international fame.
Goku is more famous it is just a fact
