I think the Archer is more fun to fly, easier to score a "greaser"
landing in, and most of all on long x-c legs (50 gal fuel tanks, yay!)
the two front seats are much more comfortable. The cabin is wider than
a 172 and there is noticeably more shoulder room between the pilot and
co-pilot. I also find Archers to have quieter cabins than Skyhawks too.
