Dell 38 UltraWide at work and a 40 at home.

I used dual monitors back from when it first became an option with 17” CRT monitors 25 years ago but you end up with a primary monitor and then other apps off to the side. The UltraWide is just easier - I can snap code and docs side by side, or two windows of code, or I can have code centered and in focus.

It’s not really a ‘downgrade’ because it’s considerably more expensive than two separate monitors but the ergonomics are so much better.
