My favorite GA plane ever was a Cardinal RG. Smoothe, spacious, kinda nice layout. A bit underpowered compared to a 205 , but still very nice to fly.
Worst GA plane ever was the Traumahawk.
Good candidate for sure.
I like the 172/177 Cessna RGs too. A little underpowered as you say, but very efficient, have a long range, and relatively fast with the gear folded.
