>> I feel ideal is ~55 inches, concave, 10 to 15K horizontal resolution. I'm with you on that. I run a pair of 27" 4Ks at native scaling, and I feel like I'm looking at a 10 year old monitor. 27" was about the smallest screen my eyes could tolerate at 1:1 scaling - I was driven by real estate more than sharpness. All other things being equal, I'd prefer a pair of 27" 8K monitors so that I can get my 4K equivalent real estate with crisper text.
