DHC-1 Chipmuck
Pitts S2A
Pitts S2B
Sukhoi Su29 ... in increasing order of everything.
C185 - everything sweet.
C206 - "Throw it in the back lets go
" (but check the CG first with a tail-dip).
C210 - Bush Rocket, but not a toy.
A36 Bonanza - 5% better at everything than the C210..
BE58 - the Tank that Flys
C 402C - great cockpit layout, everything in the right place, plenty of room.
PA31-350 - learn the systems; some designs came out of the Spastic School.
B1900D - same NACA wing airfoil sections as the Beech 18 so why add more electronics than a Lebanese drug dealer's car audio ..?
Dislikes ? Can't think of one. An aircraft is what it is. "Underpowered" is a relative term. Some things are just better than others (or won't fit in the garage).
Forgot - the 4 seat C210. Pointless - just bizarre.
