It used to be a favorite of mine as well, but I got bored with it after like 3 years or something, can honestly say I'm looking forwards to the next Smash Bros. title which is gonna be for the 3DS and Wii U though...I may get a copy for both consoles. Thinking now, there’s a Brawl Group my one digital sister made here on the forums, maybe you could join it—but to answer your question I often use Toon Link, Mario, Sonic, or Ike myself.
