I think I like the 172's a little more.. I have always thought the Pipers look cooler though so I am going to take it up a few more times to get a little more comfortable in them.
matw,
I agree, the low wing Pipers look better than the Cessnas, but I always preferred the Cessna stall characteristics. And the downward view is better in the Cessna. I did fly a Piper Tripacer a few times; it has a high wing (it's a fabric covered plane). It didn't really have a good clean and definitive stall. When you'd do a full power stall it would just do a stair-step kind of thing and never fully break. It was weird but kind of fun; just stay on the rudder pedals and bob around the sky.
