Upgraded Apple monitors are a good thing, their quality and appearance are usually a step above everyone else. That does mean a price premium, but the current prices are out of whack...there are several 6K 32" monitors available around the price point of the current Studio Display, and less than half of the XDR. The XDR price made sense as the only professional display at that level on the market, but not now.
I'm in the market for a monitor upgrade, my 30" Cinema display needs to be replaced. I'm waiting to see what Apple puts out before I jump, but right now I expect to get one of the 6K 32" monitors, they will have been out long enough that reviews of them should be pretty complete by the time Apple's monitors come out. I'm hoping Apple really puts something good forward, if they can't match what the rest of the market has going, even with a bit of Apple tax thrown in, then I'll be buying a non-Apple monitor for the first time in 20 years. That does speak to the quality of what Apple puts out, I'm not sure an Acer or LG would be that reliable for that long. I guess we'll see soon what Apple will do.
