I was using a Mac Mini, but it's back to iMac for me. Too many cables, and 3rd-party displays aren't at the level of Apple (I use a 10+ year-old Apple 24" ACD because it's superior to most 3rd-party 4k displays).
I swapped out my 2012 Mini for a 2013 27" iMac until I jump on the new 24" iMac.
The Mac Mini became a file server.
No more Mini's as main computer for me.
