So I am wondering which type of sunglasses are better: Costa Del Mar or Oakley. I have a pair of Oakley Straight Jackets, and I like them but the Lenses have gotten scratched and I really don't like that particular style. I am looking for both style and good protection/durability, and am willing to spend no more than $150.

I'm 14 by the way

It's going to depend on individual models and your own primary uses.

If I had your own qualifications, I'd probably be looking at Oakley's Flak Jacket XLJ, but they're primarily sport performance and may or may not be what you want for daily "stylish" wear.

If going for style, I might try to find a good deal on one of the Oakley Square Wire models.
