Back in 2016 I bought a XP 9550 with Adobe RGB 4K screen - mostly the display was the reason for buying, and while the screen itself was gorgeous, overall the laptop was not. The trottling would make the machine crawl at 1.7 GHZ even in low temperatures, light or heavy loads, and the amount of fan noise was unbearable - like a plane before taking off. The laptop was almost unusable for me, having to mess with ThottleStop and custom fan profiles in HWInfo a few times a year because of updates. And even then the laptop would feel more sluggish than my old i5 gen 4 desktop. A small amount of dust in the fans would make the machine restart. Even after repasting.
Dell would have other niceties in store for me. Like the rubber paint on carbon fiber deck becoming sticky after a few years. It's true what the full review say - the design being obsolete, having not even started on the right foot. Full aluminium bodies are more classy and resilient, leaving alone fingerprints. I have seen XPS with broken carbon fiber around ports and hinges, also the magnesium chassis holding the screws breaks easily.
I would never buy an XPS again, or another laptop exclusively for screen quality. The snappiness and stability are the most important even when you don't use the machine for work.
