Most of my flying has been and still is in a C152, but I have done a few hours in a Zenair CH701.
The biggest difference I felt in flying between the C152 and the Zenair is that it (the Zenair) does move about more in the air. Getting used to the shared single stick only took a few minutes, and I think it actually feels more natural to use than a yoke. The Rotax engine is quieter than the lump in the 152, and the visibility out is better. This plane has electric trim (a joy) and electric flaps. The take off run (or rather lack of!) is something else when used to the C152!
I did find landing harder than the Cessna, but that is probably just down to my lack of experience, as the angle of descent was very high - the Zenair is a STOL aircraft as well, so perhaps that is why!
