I had a Dell 38" ultrawide that I loved, but it did not survive a cross-country move so I just replaced it with a Philips 499P9H 49" ultrawide - 5120x1440 - Really the same dimensions as two 27" monitors side by side, but without a center seam

So far, I really like it - But getting it to work at full resolution with my 2013 Mac Pro has been frustrating - It essentially cannot be done at full resolution with a single cable, unless you boot into Windows (also true for Mac Minis, but apparently newer Macbook Pros can drive it) - Despite what you may read, hacks such as SwitchResX will not help here; it's a limitation of the Mac's video card drivers that Apple seem uninterested in addressing.

The "solution", for me, has to drive it using two identical Mini Displayport->HDMI cables as if it were two screens and then have MacOS treat it as a single space. Using identical ports/cables has meant the color temperature on both halves is identical and i cannot tell it is not being driven as a single display, other than the fact the menu bar is only on one half of the screen.

Aside from that, it would be nice it were higher resolution, but the older I get, the less my eyes notice and the extra width is more useful than the DPI.
