I don't know - there are deer on my street late at night and I almost could not see them with the Halogen lights. Never happened with HID (the eyes of the deer light up). I am talking high beam here.

Between two negatives, I'd take the HID over the Halogen, lol
If you illuminate the foreground very strongly, your eyes will adapt to that big area of strong illumination, your pupils will become smaller, and your distance vision will be reduced. (On the other hand, if you take the route prescribed for so long by US headlamp regulations and have very LITTLE foreground illumination, you'll have a "black hole" in front of the car, and you'll be straining to see what you're about to run over...)
Besides, if Halogen were truly much better, they would be installed on the Premium, right?
