Can someone help me out with 27” MSI 1440P OLED monitors?

Looking to buy my first oled tomorrow. Time to upgrade from a 2012 monitor that Iv been using. I play on PS5. Decided now is the time to bite the bullet and finally upgrade. Decided I’ll stick to 27”. There was 6 different types of monitors all the same size with slightly different VESA ratings. That’s all im able to notice. Which is the one to get? They rate all like $50 with each other.

These are the results on MSI’s website when I narrowed it down to 26-31”, 1440P, OLED, and MSI Console mode: 1440P 120hz, hdmi vrr support, PlayStation vrr support & hdmi 2.1 connectivity.

MAG 272QP QD-OLED X24 - $550CAD was $799CAD

MAG 27QP QD-OLED X24 - $550CAD was $799CAD

MAG 271QP QD-OLED X28 - $619CAD was $950CAD

MAG 271QPX QD OLED E2 - $599CAD was $1049.99CAD , no stock

MAG 271QPX QD OLED -$750CAD, no stock

I also plan on getting a new pc, which will also be connected to this monitor.

I thought if I’m already upgrading might as well get the best one since I plan on keeping it for a while. Any help or insight is appreciated.
