If you want better bulbs you'll have to stick with one of the OEM manufacturers like Phillips or Osram. The ballasts in our cars do not like to ignite aftermarket bulbs, and no aftermarket bulbs have been proven to work 100%.
I have the Osram Xenarc CBI bulbs, they are absolutely the best D2S bulbs on the market, but they're not cheap:
D2S: Osram Xenarc 66240 CBI - HID Bulbs - Components
