It's hard to say....
Melee had better gameplay, some great characters which aren't in Brawl like Young Link (Toon Link doesn't add up to his milk drinking awesomeness), Dr. Mario, Mewtwo, Pichu and Roy.
Brawl's gameplay is kinda floaty and slow but still good, if it had some of the characters listed above it would be even better. Online gameplay and the amount of music, level, and story mode make this game just better.
I can only hope the WiiU version have the fast paced gameplay of Melee and the amount Brawl has. Also, I would like to see some characters from Melee and LOTS more new characters, stages, musics, and some older stages from Brawl/Melee remastered.
