Mouse acceleration is IMO a good pointer to this kind of sensibility. Good refresh rates, overall feeling of smoothness, little wastes of their time eliminated, etc.
Ergonomics and sensory aesthetics are big preferences of this group. Usually they're looking to rep their OS to other people, whatever that OS ends up being, so rather than build on its strengths, they look for a specific set of strengths to which they're already attuned over time spent with other OSes. Not sure if this is you, but those of our community who are really into the objective sensory aspects are not a terribly good sell for Linux right now IMO. Heck if I can't edit mouse acceleration with ease
