Ray bans or Costa del Mars?

So I'm trying to decide whether to get Ray ban or Costa del Mar sunglasses. Ray bans look really cool (definitely more trendy) and give great protection against most types of UV light and infared if I am not mistaken. While Costa del mar sunglasses don't have very nice looking frames (they're very sporty, and not very classy looking), their 580P lenses are apparently LEGENDARY in that they protect against all types of UV light and HEV waves. And the other cool thing about them is that they give you the ability to see through the water if you go fishing.
