If Apple released a supercar for $380,000 that only goes 300 mph it would be the best supercar in the world even though the Bugatti Chiron goes 304 mph. Price is a component of what makes something the best.
Not at that end of the market. If you're paying the price of a nice house for a supercar, you don't want the best value for money, you want the fastest and that 4 mph could be critical.
In any case, there's no rational reason for buying either unless you've got a business plan to hire it out for track days or events/movies/promos, in which case its down to which one makes you the most money. As for non-rational reasons - for heaven's sake dude, you don't want to be driving the second fastest car in the country club parking lot, do you?
hey didn’t claim to have the most accurate color, or the fastest response time, or the most uniform display - they claimed overall it was the best.
When Apple launched the XDR they could have compared it to the $1200 LG ultrafine, the ~$4000 RRP Dell 8k display or various other "pro" (not "reference") displays. They didn't - they compared it to a $40k Sony reference display. That's completely binary: it can either replace a reference display (with individually dimmable pixels) or it can't.
