Acku on the Shoryuken.com message boards made a nifty post breaking down the various statistics for each character's projectile.

His listing shows the damage, start up and recovery time for the game's fireballs and sorts everything into categories so you can quickly glance at which character's projectile has the best properties when compared with the rest of the cast.

And if you want to go further, take a look at our Frame Data listings for the game where you can see a full break down of all of the moves for each character.
