I just got mine after reading this thread, using at 1440. Text is crisp, for photos Apple RGB + DCI p3 is a bit too much constrast/vibrant for casual photo editing (does not look the same as e.g., viewing on iphone/ipad), so only Apple RGB output is for me good (less pale).
A complaint is WindowServer always run with 35-40% CPU (after restarting the mac M1 it is still the same).
