If you are just looking at replacing the H7's I went for the Philips X-Treme Vision/Power; after searching around and reading Osram seemed to have shorter lives, however the Philips seemed to be on par with the Ring.
I went off the reviews on amazon and the prices were good too; made a miraculous difference on the road. Would definitely recommend paying the little bit more for a trusted brand and bulb as opposed to a cheaper one.
