Help me choose between these 3 OLED monitors — is the 321UPX the obvious choice at this price?

I’m finally moving from a 27” 1440p IPS to 32” 4K OLED and I’ve narrowed it down to these three:

- ASUS PG32UCDMZ — €820 new / €781 Amazon Warehouse (Very Good)

- MSI MPG 321URX — €749 new / €690 Amazon Warehouse (Like New)

- MSI MAG 321UPX — €629 new

My use is roughly 70% gaming / 30% productivity (Rhino/Grasshopper, Photoshop, general desktop), with an RTX 5080.

Right now I’m leaning towards the 321UPX because €629 seems like a pretty damn good price.

What I care about most is:
- Great OLED image quality
- Good HDR
- Burn-in protection
- Ideally as little panel maintenance as possible
- Good experience for both gaming and desktop/work use

I’m not particularly interested in paying extra just for additional features I’ll never use.

So my question is: is the 321URX or PG32UCDMZ actually worth the extra €120–190 over the 321UPX?

Are there meaningful differences in OLED protection, firmware, HDR, brightness, text clarity, panel behaviour, etc., or are they basically the same experience where the 321UPX is simply the better deal?

Would love to hear from people who have actually owned/used these monitors rather than just comparing specs.

Also if you have any other recommendations of any monitor I’m overlooking you can throw it to the comment section.

TL;DR: 321UPX €629 vs 321URX €749 vs PG32UCDMZ €820. Is paying extra for the 321URX/ASUS actually worth it, or should I just grab the 321UPX and call it a day?
