Anyone with Osram or Sylvania "Silverstars"?

Just wondering if anyone has either of these bulbs?

I just recently (2 days ago) threw in a pair of the Osram version. So far they are definitely whiter, and defintely brighter than the BA stockers, at least IMO.

Wondering what anyone else has experienced, and how they have held up over time (longevity).

(PS ~ I posted two links due to hearing elsewhere that although virtually the same company, there is in fact a difference between the two products... feel free to correct me if this is wrong.)
