Go and check the gallery. A side by side comparison between 15 different cars with different headlights (halogen, HID, LED). All stock and aimed correctly. Unfortunately some pictures show low beam, some high...
Nitecore MH20 NW. Plenty bright, very mature beam profile, good mode spacing, easy UI with shortcuts to low and turbo, voltage indicator, USB charging. My two little gripes - it's slightly chubby and I've seen neutral LEDs with higher CRI.
That's because of the incredible light density - HIDs are very easy to focus to throw far (smaller light source=better focus). With LEDs you need multiple emitters to achieve similar brightness but it means much higher surface area. That's why properly designed HID reflector is still far...
I think CRI is more important than color temperature. I have one neutral light (Nitecore MH20) and it has very low CRI, instead of making colors pop it makes everything turn yellow. I think 5000K is a perfect color temperature (looks like sunlight), higher CRI does the job, D4 is the second...
Distance between the dies is pretty much the same in both but in the 50.2 they're all covered with the same layer of phosphor. Single die activates slightly bigger area of the phospor than the die itself slightly covering the gap. That's why there are less artifacts.
I don't need to access all modes all the time but I'm using a couple of them regularily and I'm not the only one. Nitecore complicated the most basic thing in a flashlight and to me it's a solid deal breaker. Press and hold should be used to change modes (I'm not a fan of that solution either...
