I know I’m very late to the party on this thread, but it was helpful to me in developing the set up I have and so I thought I’d contribute.
One 4K 2019 21.5” 3.0GHz 6 core iMac with two 2013 2.9Ghz dual core iMacs (a 12.9” and a 10.5” IPad Pro. Linked by two thunderbolt to thunderbolt 3.
I have just bought the 2019 iMac, and toyed long and hard with getting a Mac mini and two 4K curved monitors. However, the sleep/wake issue and the resolution scaling problem resulted in my buying another iMac and using the other iMacs as target displays.
I use my iMacs mostly for word processing and require multiple screens for many documents (from which I compose my research). I may yet move to one 49” curved monitor because the set up I have now is less easy to look at than curved screens, but right now I’m happy with how it sits and I enjoy the ability to split each screen on the monitor into two giving me easy copy and paste functions from other documents.
