I haven't used Gatorskins (or Armadillos), so I can only go by reputation: The Gatorskins should be tougher but slower.
I've put 2000 miles on Conti Grand Prix 4 Seasons (28c) without any flats, and mostly replaced them as a preventative measure. I think I'm on 1000 miles on the Conti GP4000s 24's I mentioned, no flats yet.
Something to keep in mind, if you are riding at 15mph or less you can use wider tires, up to 25c's, without taking a performance hit. If you're comparing a 23 and 25 of the same tire, the 25 will be slightly less aero (which doesn't matter at 15mph or less) and have slightly better rolling resistance (which improves performance at these slower speeds).
