I've done about 100 hours in each, and I prefer the Cessnas. Extra door, more room inside, no bar going down the middle of the windshield, feels more like I'm a part of the airplane instead of just strapping myself into one. I've found that I can consistently grease landings in a Cessna, but not in a Piper (likely because of the low wing or just that I did my PPL in a Cessna . . . I have no idea). Also, the stall warning horn in the Cessna is just a reed and not electronically powered, so it produces a higher-pitch sound as you progress towards a stall; in a Piper, it's just the same whine no matter how stalled the wing is. The high wing is great for cover when it's raining and sightseeing/ground ref maneuvers, and it's easier to sump. The Pipers do have those manual flaps, though, which are pretty cool (especially when you pull them all the way back to 55 degrees
)
