Now... don't laugh, I am of limited experience:
LOVE:
Cessna 172: Very familiar. you just sorta sit there and the scenery goes past you. Know most things about it and no matter where I went, I could be flying one after a 45 minute checkride.
New Cessna 182: Just goes up and up and up! Takes the gusts and turbulence easily. Autopilot. Fits everyone on board.
HATE:
Grumman AA-1: Engines cut out on the landing roll if you're not careful. Too comfy for comfort. Stall, spin, crash, burn die. Richard owns one.
Ardmore's Cessna 150 tailwheel: Even more 'comfy' than the Grumman. Tail will snap off if you're not careful when landing (tailwheel conversion doesn't include strengthening aft fuselage). Takes 25 miles to climb to 3000' (at 55mph).
