I have been a dual external monitor (plus laptop) person for many years but both Apple and Zoom appear to continually have more and more issues with dual monitors, especially on the new hardware where everything must be connected via dongle.
I primarily rock the laptop one as my mail client, the one external in landscape (primary monitor for most everything) and one external in portrait (Calendar, and multiple chats or for use working on writing long documentation pages). That way the that comes to me is always open on the sides but I can stair ahead and focus on primary things. Not sure if actually distracts me more or not but its what ive grown to like.
As for issues, sometimes waking from sleep it forgets which monitor is which so the two externals are both flipped 90 degrees. (I mostly fixed this by using two different dongles, one apple and one third party). Even assigning things to specific desktops doesnt always work. I purchased the app Stay a while ago which helps my computer remember where to put things on my multiple monitors but it doesn't solve the other issues. I also got the app Magnet to help size windows on a screen to better fit to different grids based on key strokes.
In the end it comes down to personal preferences and workflows.
Even though I have always liked the dual setup, due to regular issues I am actually changing my setup and I am currently waiting on a delivery on a new large single monitor with the hope that it will reduce my pain points.
