Who is better Sonic or Mario

Depends in what respect:

• Mario is a lot more famous worldwide
• Sonic is a lot faster than Mario
• Mario has more strength than Sonic
• Sonic can cut through almost anything when he's spinning

You can have a fight between Mario + Sonic on Super Smash Bros. Brawl for the Wii.

Overall, they are both heroes in their own games. In my opinion, Mario is better. Sonic is just faster, but Mario saves Princess Peach from the trouble she gets into numerous times. Sonic cannot compare to that. Sonic has done some good deeds, but he has not compared to Mario's heroic actions
