I'm using a 40" 5K Lenovo P40w-20, it's a 21:9 (5120x2160) IPS panel with 75 Hz refresh rate.
The problem with 2 monitors is that for me it inevitably falls into a "primary" and "one I occasionally glance at" pair.
With 21:9 I split into 3 columns which are 7:9 each and still have enough pixels (~1700x2160) for crisp text. Browser on the left, IDE in the middle, and terminal on the right. I very rarely use any other windows, so having everything accessible at a glance is great.
It also charges my laptop at 96W via Thunderbolt 4.
The only issue is that this panel (used in Dell and LG 40" too) is somewhat dim.
