Glider: The KA6E.
Looks beautiful, handles like it looks. 1:34 glide from a wooden glider, it's just very nice!
Light aircraft: There is only one!
It looks good and it's handling is the best of any small piston I have flown, including the aforementioned SF260 which is nice and powerful - but doesn't quite match the Chippy for harmonised handling.
Fast Jet:
OK, so it's not really a proper fast jet - and I haven't flown many of them. But it flies beautifully and just looks the business. It just could use a bit more power though.
Bomber:
It has the look that says "Death and destruction is coming your way" and flies pretty mean too!
Airliner:
It looks right and is the nicest handling big jet I've ever flown - a real pilot's aircraft. Nicer to fly the 747-400 which somebody mentioned, in fact the Classic 747 is nicer to fly than the 400.
