Meh, I tried Silverstars and the Ultras a while ago. Switching from the stock bulbs, I did notice a bit of a difference, though I think at the time, I was more impressed with the color difference. Once the newness wore off, though, I did notice how hard it was to see the road when it was, say, wet. The reflective lines showed up nice, but that wasn't much use on some of the more worn roads around here.
Tried HID PnP in the lows, and it is definitely brighter (duh). Your problem, OP, is that you went with 8000 K. That's too blue. You should have went 4300 K, maybe even 5000 K.
Yes, projectors would be better (not the ebay crap, actual OEM/reps of OEM projectors), but at least on the 2nd Gen lights, the low beams aren't horrible with HIDs, at least IMO.
If you're going to stick to halogen, try to get something that isn't colored since that filters out some usable light (usually your yellows).
