Too small… I got used to my 4K Philips OLED 42" that I hung directly on the wall in front of my desk (no stand at all)… USB-C cable also charges the MacBook.
This size is so good to work with; so much screen estate.
You're using the pixels for something different than the target audience.
People who want a Studio Display want retina crispness. If you enjoy a 42" 4k, you're more concerned with real estate than image fidelity.
I'm happy with a 65" 4K TV in my living room, but a 4K 27" monitor is borderline too low-res for computer work. Same pixel count, but different use cases.
