EVO-2 aren't newer, they've both been around the same amount of time.
They simply have a moulded plastic ratcheting piece with decoration, opposed to the basic metal ratchet on the EVO-1. Therefore the EVO-1 ratchet is going to grip better, but it also means it's going to wear the binding down a lot faster too, as the metal will cut into the plastic easier. However, they are stronger, so it's a payoff of strength versus lifetime.
There's no different price or quality-wise (if you incorporate how much longer the EVO-2s might last), the main difference is that the EVO-2 look nicer
