So I have one and find it's a great fit, not for the Mac Studio but as an accessory to my 16" M1 Max MacBook Pro.
The screen starts up instantly (and always), unlike the previous monitor which had a delay (when it would turn on at all). The monitor provides 96 watts of passthrough power so I have a single cable attached to my notebook. And as you mentioned the very same Thunderbolt connection also allows me to plug my additional devices (storage, backup) directly into the monitor and still get high-speed data transfers, eliminating the need for an additional hub.
The monitor is bright, color accurate, and sharp as a tack. (A feature that that my somewhat aging eyes greatly appreciate.) I wasn't sure about the potential for glare, but is use I've found that Apple's anti-glare coating works extremely well. So well, in fact, that I'd think you'd have to have a window or bright light directly behind you for the nano texture option to make sense.
The height also works well for me, so all in all the base model is a great fit, with no need for the additional (and somewhat pricey) options.
I find it somewhat amusing that you dismiss the look and build quality as, for me, that's one of the things that I appreciate each and every day. My job requires me to stare at these things day in and day out and if I have to do that, then if I have any choice in the matter I'd prefer not to have to stare at some wobbly piece of plastic "budget" monitor.
Would I like it to cost less? Sure. But I could say that about any premium Apple product.
Is it a value product? No, it isn't. But then again, it could well depend on just what it is that you value...
