I have the Kerosenes too. I think that like much of anything in cycling, it's all about the fit. Unfortunately, this may be a problem for you since you can't seem to find either in local stores. I think both brands are of equal quality and some people claim that Oakley's are better quality but my close inspection makes me believe they're on par. This can be said for both the frames as well as lens/optics. Oakley does offer the ability to embed the Rx lens into the wrap if that's important to you. I thought it would be great to do that but then interchanging lenses would get really expensive as I'd have to get multiple Rx lenses embeded... one for each wrap. In the end, what really drove me towards the Kerosenes was the adjustable temples and nosepiece... especially the nosepiece. I simply could not get the Oakley M-Frames to sit properly on my face while the Kerosenes fit perfectly and comfortably once adjusted.
