I have both sets you guys are talking about, both seem comprable to me. I liked the oakleys because of comfort and because the oakleys are interchangeable with their lenses I have a pair of amber and a pair of smoke lenses depending on what the conditions are like.

For the Smiths I also got the photochromatic lenses in the smoke which I really liked, the Smiths also had better coverage on the eyes to let less light behind the glasses

I feel like I had better luck matching the conditions with the oakleys and both lenses

Both pairs have their advantages and as for the ability of the polarization I feel that they were matched up equally.

I would not hesitate to purchase another pair of either of the brands when time comes.
