I used to think HID was the end all be all for lighting performance in both output and longevity; I think most of that is attributed to how long HIDs have been around and they're so "tried and true" and my personal experience with aftermarket (and OEM) HID systems, headlight retrofits, etc; The reality is LEDs have come a long way and they've only just begun to be utilized and optimized now by OEMS and projector manufactures. Now don't get me wrong HIDs do have their place, but the more I've learned about LED vs. HID I really feel like it depends on the application. Each lighting source performs differently in different headlights and they each have their pros and cons.
For example; In my '15 Yukon Denali XL I have OEM HIDs with D3S bulbs. I've upgraded my HID bulbs to OSRAM CBI's, they perform ok, but coming from someone who previously DD'd a vehicle with an Acura TSX projector retrofit they leave a lot to be desired still, but maybe I spoiled myself in the lighting department? Then I drive my friends 2018 Acura MDX at night and the light output from those factory LED projectors is insane, and they're stock! Which leans me towards GM just sucks at headlights and lighting output. Our GM vehicle platform is not the only one that has had ****** headlight performance and output over the years.
All that being said I can say with confidence that the light output in the photos that STORMIN08 have posted of the Morimitoro 2-Stroke 3.0 LEDs in his OEM Halogen projector housings exceed what my OSRAM CBI HID bulbs are putting out in my OEM Denali HID projector headlight housing.
From a big picture perspective IMO HIDs have kind of already "peaked" in their performance offering and bulb development amongst the OEM manufacturers; Whereas LEDs still have a long road of further development potential ahead of them.
Regarding the headlights you've linked in your OP if I'm being honest I feel like the words "custom" and "upgraded" are used very loosely to describe them, but that's just my opinion.
If you really want a complete upgraded headlight assembly that looks "different" than stock and performs better you really have 1 option:
The new Morimoto XB LED headlight assemblies:
(1) 256% Brighter Headlights for your 2015 - 2020 GMC Yukon Morimoto XB LED Headlight Install and Review - YouTube
(1) 2017 GMC Yukon Morimoto XB Headlamp Installation - YouTube
Cheapest price I've found online - $1,275
Morimoto 2015-2020 GMC Yukon XB LED Headlights - Function Factory Performance (ffperformance.co)
If you want to upgrade your headlights for better performance and light output while still looking stock for an OEM+ route
A headlight projector retrofit -
Can be more expensive than the option above depending on if you're doing the work or paying someone.
May or may not include having to purchase an additional set of headlights to retrofit depending on if you're doing the work or not and to avoid downtime of use of your vehicle.
