our 04.5 2500 duramax had great headlights, especially when wired to have all 4 on with high beam.
2015.5 gmc denali was pretty bad when I got it, I complained and it turns out they had a TSB that changed tbe bulb type and wiring and made them much better but not as good as the 04.5.
my 97 Mercedes SL500 with the U.S. code headlights were terrible. switched to the european code headlight assemblies and bulbs and made a major improvement. Amazing how much better they are.
