Ask HN: Best ultrawide monitor for programming and gaming?

I work from home and have a Windows PC for gaming and have a Mac for work. I plan to buy a KVM switch to make it easier to switch between the 2 and to allow me to share my mouse and keyboard but would like to also use an ultrawide monitor for both since it seems most affordable KVMs are 2 ports.

Any suggestions? Also open to normal monitors that can properly daisy chain for both Windows and Mac using a DisplayPort KVM but my understanding is DisplayPort daisy chaining doesn’t work on Mac.
