Well...whats cooler than an Italian plumber who can grow larger and shoot fireballs, certainly not a giant ape that plays the drums (as featured in donkey kong 64). But on the flipside Donkey Kong didnt have an awful movie. But Im still goin with Mario
I Loved The First Donkey Kong Game! Woth Mario In It! That Game Is So Fun To Play! Its So Original, But I Hafta Say Mario Is Better. Hes A FAt Italian Plumber Who Always Wears Red, And Saves This Blonde Chick From A Dinosaur. And Donkey Kong Is Just A Huge Ape..... MArio All The Way.
Mario is more classic and more well know they don't make that many games with donkey kong as main character. But the do use him as a secondary in smash and that Mario racing game.
