Re:
Without knowing the difference in watts and temp, its kinda hard to tell why.
There are a few factors at work here...
Colour temperature is very important for 2 reasons:
-Light transmission: Cooler look lights (higher degrees K), you know the ones that give a cold blue look, actually have lower lumen output than warmer (lower temp) lights. The sweet spot depends greatly on what type of light you have. No i don't know the best values off hand 
If your new lights are the same watt, and i assume cooler (higher temp K), then maybe you are getting away from the sweet spot for filament bulbs and losing lumens.
Does that make sense? The watt rating is watts CONSUMED, where as lumens is the light OUTPUT. You can have 2 globes with the same watt consumption, but different light output based on what temp they are.
-Our brains: Are used to seeing everything in daylight, or ~5,800K. Anything lower (almost all filament bulbs) will have a warmer look. This is still ok for us as its often closer to dawn and dusk light, and pleases the caveman part of our brains that says warm yellow light = cave fire = good for caveman.
HID's on the other hand were specifically designed to be as close to sunlight as possible. This gives them the best lumen output while giving us a familiar light that our brains find much easier to process images. The only reason HID's come is stupid 8,000k+ temps is for show. Their output is greatly reduced, and as we never see anything illuminated in that temp, you guessed it, our brain has a harder time processing.

Re:
Rick,
4300K is colour temp. You need to tell us the wattage of the HID bulbs you bought.

Re:
The thing with the Phillips bulbs always been an excellent brightness and colour temperature, but they didn't shoot far enough compared to the factory bulbs. It has nothing to do with them being H11 or H4 I reckon.
If you invest in a more expensive bulb like the PIAA or IPF Fat Boys, you will notice a HUGE difference in terms of distance illumination but the colour of these bulbs is very close to standard. The Fat Boys are amazing to be honest.
Do a search on them and you will find some pics on the forum.

Re:
It depends on what you want to achieve Rick
1. Factory HID look
2. Better road illumination in Lo beam
3. Better brightness
