Unfamiliar with the 308. Of the three others:
ankle stability: about even.
comfort: Res4 and SFX about even, maybe slight edge to Res4
ventilation: Vapor by a country mile
lightness: Vapor by a country mile
I really dig the Res4 as a comfort shoe, but I feel much lighter on my feet and quicker to the ball on that first step/pivot with the Vapor.
