I think there is a pretty small chance of this being settled once and for all because aesthetics is subjective and there are number of factors at work.
1. People have a tendency to prefer what they're used to seeing. I don't know if the same is true elsewhere, but here the fashion in clothing has recently changed to have a high waist and it looked very odd at first. I also remember it looking odd when the fashion went the other way, i.e. the waist band of clothing went down to hip level. It also wasn't so long ago that Simon Cowell was made fun of for having an unfashionably high waist.
2. People are influence by cultural attitudes. Here's one example:
I prefer the aesthetic CUT cock look 100%. An uncut dick looks like “someone“ left the ”job” unfinished. A high and tight Circumcised cock looks clean and complete in appearance with the very sensitive scar hi lighting the very fact that CUT dudes are, in fact, quite proud. I do not understand why anyone would prefer the look of a malformed cock.
So "looks clean" - relataed to an American obsession with cleanliness. Not that people from other nations don't like to be clean too but we don't seem to have the same obsession with it. Also, "job unfinished" as if inaction is some kind of sin.
Neither of these is innate - they are learned values. A good deal of invention comes from a dislike of work - from people contemplating "If only I could make a machine to do this job I would not have to do it myself".
Here's another one to prove it doesn't just work the one way:
...Most circumcision scars are kind of revolting to me. I don't understand why anyone would prefer the look of a mangled cock.
Again a dislike of scars is not innate. The next sentence gives the game away when calling a cut cock "mangled".
3. People don't want to believe that something that has been done to them is actually pointless so, given the very sketchy evidence of any health benefit, they have to believe in some other benefit, like "at least it looks better".
So, after that, you won't be surprised to learn that I am uncut and, though it is not a strong preference, of the two I prefer uncut.
