I think if you took a poll on this forum, HID for low beams and LED for highs and fogs would be the best choice for the headlight housings we have - and I mean the 2014 - current.
I experimented with the H9 low and 9011 high conversion and while it does improve visibility, it also increases current draw - albeit marginally.
After that, I tried LEDs in my low beams and they were a disaster. Maybe there are more companies out there building bulbs specifically for our headlight housing now and they may have improved on it. Issue is, our low beam projectors weren't designed to direct-fit a LED bulb - unless one is custom designed to fit our housing. When I tried the LEDs, I lost all side lighting on the road and visibility was dismal at best. Again, this technology is improving everyday, so it may be worth researching.
I ultimately decided to go HID for low beams and I was very reluctant at first but after I installed my xenon depot kit, I definitely noticed a great improvement over the stock setup. One word of caution, Xenon Depot's customer service left a lot to be desired when I ordered my kit, not sure if they've gotten their act together now.
As for high beams, I went with LEDs and ordered a set of DDM Tuning 50W 9005 LED bulbs - intense bright light when you need it. For fogs, I installed a set of Diode Dynamics H11 XP80 LED bulbs and they have been outstanding.
I'm very happy with the above setup, although I'm sure in the future I'll be looking into LED sets for my low beams, since this technology is developing at a very fast pace and I think some good products will become available for our trucks. HID is an aging technology but in our headlight housings, I've come to realize it is the best aftermarket option. For now, I'm good with what I have and I've had no issues whatsoever and am definitely enjoying night driving again.
