As the owner of a 152 it gets my vote. Allthough I did not learn to fly in one I converted afterwards and bizzarly got hooked on them! Mine has a full IFR fit with GNS430 etc and I love it.
I fly loads of different aircraft ffrom the C152 through warriors, arrows etc. all the way to complex multi engine. But everytime I get back in my 152 it's like coming home!
