Generally when you can’t discern the rational for a preference, it often means the underlying basis is associative rather than objective. That’s how most of us discern most things most of the time—a particular appearance tends to correlate with past performance.

You’ve probably read a bunch of very good papers typeset in TeX.

What I mean is that, with some things like music, I can say that this recording is better than this one because the musician is playing with better dynamics, or better pacing, etc, but with two chocolate cakes from a restaurant I can only say “this one is better.” I can’t give any advice to the chefs. Typesetting is like the latter, I can say “this looks better” but can’t say “it’s because the margins are wider” or the serifs are fatter.
