There's a good article in the current issue of Velo News. It compares eight wheels including Enve's 3.4 which came in second to Zipp 303s (not the 202s you are considering). I've ridden Enve's and like them. I also had the Zipps and they are great for climbing. Based on what you said, I would go with the Zipps. The hubs aren't great but just require more maintenance.
