Personally I think there are a lot better training aircraft than any of the Cessna/Piper aircraft, not flown the Tecnam so I cannot comment there but the Pa28 and Cessnas are designed to be "driven" from A to B with minimum interference from the "pilot", get something like a Tiger Moth, Chippie or, if you want to go nosewheel a Beagle Pup or Robin and you will get an aircraft that needx a bit more flying but is actually more fun, unfortunately any of these aircraft will cost a bit more to run which is why the Pipers and Cessnas win out!
