I personally like the physical separation of the screens because each screen performs a job and those jobs I prefer to be static in position. I have 4 screens total at my Office station all on adjustable stands. From left to right I have
22" / 27" / 27" / 22"
My left most screen is mostly out of my field of view and as such it's dedicated to fun. (Youtube/Twitch)
Left middle is my main screen with my icons and is also where I typically perform all my remote support
Right middle is a screen dedicated to chrome and I typically have 6 tabs open (Email, Calendar, Invoicing, Google Messages, Syncro) I also use this screen for web browsing.
My right most screen is for the tools I use regularly and all day long. (1Password, Google Finance, Google Notes). When I am working on something and it gets put on hold for one reason or another like when I can't get ahold of a client or I want to remain logged into a tenant but can't complete what I am doing it also gets moved to this screen for later use.
