I like the NRS Freestyle the best. I also have the Comm 3, but I really hate the zipper and velcro system that's on them. I'm a "no fuss" kinda gal when it comes to gear. The Freestyle's are super comfy, warm, flexible, and I've done some pretty good side hikes in em. The Desperado looks to be exactly the same except a thicker sole with better traction.
The Loyaks look nice, I just don't know how I'd feel about a regular shoe... I like that the booties fit like a glove and don't fill up with water. Nothing worse than feeling like your shoe's gonna fall off during a swim-- well I guess I should say, your shoes are the probably last thing you should be thinking about during a swim, eh?
