It really depends on what I am after sonically. In most cases I am happy splitting the difference and going 25. Not sure how scale length provides better upper fret access though in your initial statement. Maybe I am misunderstanding?
The difference between a Gibson and Fender scale is three-quarters of an inch, spread across over two feet. That means each fret is about 34 thousandths of an inch further apart on a Fender than a Gibson. That's about the thickness of a Yellow Tortex pick. Not trying to say it doesn't make a difference (as it obviously does), more of how little it takes to make a difference.
My preference is I don't care. I have all of them, including a multi-scale 8 string that goes from 25.5 to 27.5. Whether they're setup properly makes about a zillion times as much difference as the scale length.
Easy answer is up above the 12th fret things get more cramped the higher you go. Playing really high up the neck I find the 24.75 really tight above the 17th fret.
Been playing mostly 25 scale since 94 or so when I built a couple Carvin DC's and fell in love with that scale. Been mostly PRS or Carvin Kiesel guitars since.
