4k Curved Monitor suggestion for 5090

I currently have a Samsung G5 Curved monitor. Love the size and curve of the monitor. But I know it’s not doing my 5090 justice, especially when I look at all the pictures here lol

I am getting confused on what is newer and what is older in terms of monitors. Looking for some models/suggestions on what I should go with in terms of a curved 4k.

Thanks!
