Jones has already beaten most of the top guys in his division, while Aldo has yet to face his greatest challenges, seeing that his division is not as stacked. Knowing Edgar, if the fight is close enough to be slightly controversal, he'll ask for a rematch, and he'll probably get it. Jones still has challanges ahead of him (Cormier, Gus, etc...) while Aldo is more likely to move up a weight class.
So if I had to flip a coin and guess, I'd probably say Aldo.
Basically what it comes down to is which fight is going to happen sooner between Jones/Cormier and Aldo/Edgar, and which champion is more likely to defeat his toughest challenge.
