I hope you're not thinking of putting those D2S bulbs right into your headlamps without modification...
As for brands, I would stick with well known brands like Philips, Hella, Osram, Narva, or Sylvania. I never heard of Pilot and would be weary about their quality.
The fact that there's a 9006 or 9005 plug on the ballast really makes me weary because you're not supposed to just plug a D2S capsule into the housing where a 9005 or 9006 bulb is supposed to go. The lamp housing is designed to utilize the light output from a 9005 or 9006 bulb, not a D2S bulb.
Unless you plan to do a propper retrofit, ie fitting the lamps from a vehicle with HIDs into your Camry, don't do it.
