I had the 32" Samsung Space Monitor [0] and I loved it but I wanted another 4k monitor on the side. The 57" Odyssey G9 is literally two 32" side by side without notches or a bar in the middle, so I went for it [1]
Honestly the curve is maybe too much, but I haven't tried a 49" or seen it IRL so I cannot compare them. I got used to the 57" in just a few days tho, and now I'm deeply immersed into everything. FancyZones is good enough for my needs.

The curvature is indeed a bit much in the beginning, and I would like to try something like the Xeneon flex next, where I get to choose the curvature.
