I have flown the lot and I suppose my viewpoint is coloured by a desire to purchase rather than to rent.
A PA28 is old, primitive and very much a 'Spamcan' The favourite of flying clubs as they are cheap to buy and maintain.
A Tecnam is modern, cheap to run, expensive to buy and is light. That is the rub... one cannot fly IMC or carry much. That may not be a problem for you.
However, if you were to hire a car, would you hire a Fiesta or a Healy 3000? I suppose it is all down to what you want to do with it. Same for aeroplanes. I'm very much biased towards Bulldogs and opted to buy one instead of all those ultralights/microlights.
