Had a Cessna 172 for 5 years. ..... For some reason, I did not grow to love that plane.
I flew a C172 a fair amount in Hawaii. It was okay but not great. I also flew a C182 a bit over there and didn't care for it at all. However I loved the C206 which I flew a lot on wheels (they're dogs on floats).
My wife and I took our honeymoon up the Inside Passage into SE Alaska and the Coast Range of BC in a C180 on floats. However, it was a C180 as re-engined by Kenmore Air Harbor. For reasons too lengthy to go into here, they wanted to be rid of the 0-470U engine (230hp) in all their C180s so they took the Continental IO-520 engine that was used in the 185 and 206, removed the fuel injection system, installed a modified carburetor from the 0-470 (fuel injection can be a pain in the a$s in float flying) and created a 270 hp (constant rating) engine that was given the designation 0-520KAH.
A forty-horsepower increase may not sound like much, but with seaplanes there's no such thing as too much power and any increase, even a small one, is a Good Thing.
For a small plane, that re-engined C180 is really a great machine.
