IMO, the best MacBook monitor is the LG 38WN95CW ultrawide monitor [1].
Pros:
* Larger 38" screen
* 90w charging
* Thunderbolt 3 (like USB-C but better)
* 144hz refresh rate
* 1ms response rate
And current generation MacBooks only support one external monitor, so two 27" 1440p monitors should not be recommended. And there are methods to having more monitors, but they require additional hardware and do not always work well.
Cons:
* Hard to acquire (out-of-stock everywhere)
* Very expensive ($1,500+)
* Cannot natively control brightness & sound via keyboard like other LG monitors, but software [2] can add this feature. Though, this is currently broken for all M1 Macs.
I've been using the cheaper ($1,000) but very similar LG 38WK95C for around a year. I have it attached to a Mac (via USB-C) and a PC (via DisplayPort) and the only drawback I've found is that when you switch inputs it "disconnects" the other input so the Mac thinks the monitor has been unplugged; my previous monitor did not do this.
Do you have a sound bar or external speakers? If so, I assume you only have one of your devices connected to them? With USB-B the audio source is determined by whatever device is currently selected by the monitor. It's nice.
I used to use a cheap mixer[1] but recently I found some speakers with multiple inputs. It would be great if everything could just route through the monitor instead.

My monitor supports Thunderbolt 3 daisy chaining - Connecting a thunderbolt 3 upstream port to the input of the 2nd monitor. Do you know if two monitors setup this way would work with a MacBook?
Another con: no upstream USB-B port for connecting to a PC. Also might be hard to power with a graphics card given the higher rez. Sounds super nice for productivity though.
Not really. How do you connect the PC and MacBook to the sound bar? If connecting both directly to the sound bar, you'll need to switch those too. So each time you want to switch between PC/MacBook, you'll have to:
1. Switch the video source on the monitor
2. Switch the USB destination on your USB switch
3. Switch audio source on your sound bar
That's why upstream USB-B is so compelling. The monitor acts as a full KVM.
