More specifically, HID is a subset of Xenon. There are (incandescent) halogen bulbs that contain traces of xenon gas but their marketing wizards label them as 'Xenon lights' because people will equate xenon with bright white light. Just FYI..

No, the color temperature of the bulbs has nothing to do with brightness (or lumens). It's just coincidence that most 4100k-5000k will outperform 6000k+ bulbs. That's because some bulbs labeled 6000k+ are actually just 4100k bulbs with a color filter on the capsule.
I think the disagreement is coming about from the definition of performance. Milan, you are correct that D2Rs are for reflectors and D2Ss are for ellipsoid headlights. However the D2R capsule was never designed for use in halogen headlight assemblies. Though our headlights are the reflector type, they were designed for halogens bulbs not HID capsules. So the discussion on which bulb is the proper application is a moot point, since their very usage is exceeding the design of the headlights.
Now, if I understand Antonio correctly, he's saying that the D2S capsules create a better light pattern in our stock halogen headlight compared to the D2R. From other readings, I understand that the light color is usually yellower than expected, again as as result of using HID capsules in halogen headlight assemblies, thus the demand for HIDs with higher color temps.
