Bearing in mind, OP's MacBook Pro has non-integer scaling, as do all of Apple's laptops.
Very good point. Still, switching to integer on those you're still in the ballpark of typical Apple scaling, so you can make a choice between screen real estate and exact pixel alignment without the integer choice being an awkward size.
Anyway, it was just one of several choices for me that I wasn't sure whether it would bother me or not, and the shutdown took away my ability to audition the choices. Mostly it was being unsure where I'd be as happy going from 24 to 27 as to 32, being unsure whether non-integer scaling would bug me, especially for panels where the closest integer scaling choice would be particularly bad, size-wise, andat least to a very small degree, whether it would but me staring at a pair of cheap-looking enclosures (if I didn't get the XDR, it would have been two LGs) would bug me. (At least with my old/current setup, the LED Cinema is even today a good-looking display, and my old Cinema HD not bad.)
In all, I figured if I liked the display, I'd have trouble regretting spending such an insane amount on it. In absense of being able to try them, that was the deciding factor. Many people think it's insane to buy a BWM over a WRX, what you get for the $, but there are probably few BMW owners driving around with regret they overpaid and should have gone with the WRX, so to each his own
It helps that I've been able to go many years without buying a new Mac, due to slower advances the past decade, hpe this one will do for a few.
Just my rationale for my choice, I can certainly see the point of view of those who like the ultrawide configurations, Dell 8K, even they insanely good bang/buck of some of the 4K displays. But for the integer-scaling + retina + same-size-UI want—if that's important to a person—unfortunately the field gets pretty narrow, wish it weren't so.
