snuggles, that thread I linked you to is over three years old.
I have actually tried the following:
Ion Crystals (yellow), Xtreme White (4300k), Super Plasma GT-X (5000k), and Sylvania Silverstars (4000k).
The GT-X are nice but nothing came close to the HID white. Personally, I like the yellow (Ion Crystal) the best. It gives a GS/IS sort of look to the car, but they are not as yellow. Plus, they do add some help in fog and snow with the yellow. But like you said, the HID pretty much overshines any white fog bulb.
When the GT-X burn out, I will go back to the yellow.
