nice to see you back again! I totally agree with you. Once you pass the "good enough" level, different criterias play a role.
I could not describe it better, so I quote it from you "...but they do not necessarily mean the Image Qualities produced will meet a person's aesthetic criteria..."
This is where the differences of the different sensor formats, MP counts, lens choice etc. kicks in. Especially DOF and great bokeh is for example something, I miss the most with MFT and APS-C. Only for this alone, Medium Format would be lovely...
