Oakleys are made pretty well, but if you dont want the branding, you can get plenty good frames for less cash. I used to get designerish frames till I discovered a place that sells hand made generic Italian frame & lens for $150. I also highly recommend going either rimless or semi-rimless--it truly improves visual comfort more than anything.
So I think they look decent, though straight temples can be annoying at time. My heads virtually shaved, so they dont bother me much, as my sunglasses have them. If you look good in them get them, but you can find a similar shape in many different variations, and without the cheap looking two-tone. Might look good on you, might not.
Oaklies often have a warranty, which they better considering the price, but I personally dislike logos on glasses--you might like that.
Try on a pair of the rimless titanium frames that have come down so far in price these days. Youll be surprised at how they disappear. In the end, there are a lot of cool glasses, but few that fit and feel right. Mine do both thankfully.
If the Oaklies fit the bill for you, you know what to do.
