Sonic is better because he is fast, slender, powerful, and has a nice fan-base. His cockiness helps create a nice personality. Also, like I said in why he is better, Sonic has a bigger fan-base. How do I know? Well you see, there's this little thing called Fanfiction. Heard of it? Good for you. Anyways, at the moment there are 25,082 Sonic fanfics that I have found on a website (no I did not count them all) While as Mario has 5 thousand something.

In terms of powers, Sonic wins. His many forms give him a better advantage. Sure he needs to collect all 7 Chaos Emeralds before turning super, but he can still do much more without it! Also, don't give any crap about how Sonic is unable to swim. All heroes have weaknesses! If they didn't, they would seem too powerful, which would make the government fear (G.U.N. people!) Plus, an all-out powerful hero is a boring hero.

Mario is fat, ugly, and stupid. Can Nintendo make an original plot-line, for like once! All he does is save that damn Peach from Bowser.

Sure Sonic kind of has a same plot-line (always out to defeat Eggman), but SEGA is always changing it up. So many twists and turns along the way! Plus, in Sonic and the Secret Rings and Sonic the Black Knight Eggman didn't even show up! ORIGINALITY! Also, in Sonic '06 (which every Sonic fan knows sucked) Mephiles was more of the villain then Eggman, all Eggman did was kidnap Elise and be a partial reason for the release of Mephiles. Speaking of which, Sonic all has awesome villains! I mean COME ON Mephiles was just EPIC! Great voice, awesome theme, has a crystalline (I think that's how you spell it) form, and can kill you in a second. I would love to see Mephiles against Bowser hehe.

Okay, off topic a bit. As I was saying, Sonic has VARIETY! Now, please I would love to see you Mario fans tell me how he is better. Try and make him sound more epic compared to this information. I dare you.
