Which Is The Strongest?

Which starter is the strongest amongst STABing? because I got my pokemon pearl today and I'm starting my adventure now.

EDIT: Nevermind, my cousin told me that CHIMCHAR was and I'm so excited that I got an ADAMANT CHIMCHAR.

I think you should just play whichever one looks like it would be the most fun, then worry about real battling and stuff later. Just have fun with the game, don't take it too seriously.
