I'd been using 2 external displays with my macbook pro for the past few years. The most annoying thing for me was waking the mac from sleep and getting it to detect the two of them. Once they were both detected I honestly thought the experience was OK. But the dance I needed to do every time to detect was so frustrating that I recently replaced the two of them DELL's new 40 inch 5K ultra wide: https://www.dell.com/en-us/shop/dell-ultrasharp-40-curved-wu.... I'm very happy with it. For my (slightly aging) eyes the pixel density is great, there's lots of space, and the waking from sleep detection issue is finally gone.
