If Urijah Faber fought Frankie Edgar at a Catchweight fight, who would win?

Urijah is a very good fighter but Frankie would most likely win. Hes very fast, has a wrestling advantage but stylistically Faber could win for sure. Edgar is a very good fighter but honestly I think Penn beat him 49-46 the first fight and I think the only reason Frankie beat BJ the second time was BJs laziness.
