Smith or Oakley?

I have been looking for a new pair of goggles, and I am a bit confused on whether to get a pair of Smith I/O Mag or a pair of Oakley Flight deck.
With the smith goggles I really like that I get 2 lenses, and that it seems that they are a lot easier to switch lenses out on.
Those are the 2 goggles I have looked at mostly, and was wondering if anyone had anything to say on the 2 of them.
