Grudge Match: Quasar vs Firestorm

Given the sheer powers of both Quasar and Firestorm, such a fight would be monumental. No way would it be one-sided. However, pressed to call a winner, I'd give it to Firestorm because he can transmute inorganic matter and energy to whatever he wants. He ought to be able to think of something to hit Quasar damaging enough to win.
