Well, everybody's got their favorite goggle system, and some people will tell you to get this or that, because of sponsorships. I got a set of JT Ize's, Proteus, and VForce Morph. I like all three. The best you can do is try before you buy, since you'll be wearing them for sustained periods of time, you don't want anything uncomfortable on your face. Some people love the Proteus (like me), others feel it's to close to the face. Some people like the new Dye ones, some people think they pinch the nose too much.
Try on several sets of goggles, and go with the most comfy ones.
