Most twins are also going to be constant speed props and retractible gear, if not high performance, so that gives you an even greater level of complexity/control/speed/fun than you're going to get in a light single.
Ain't that the truth! Of course, even if your twin has under 200 hp per engine, it'll have two of them so it'll make more power. To me, the complexity is fun. Let's think this out.
172 takeoff: Mixture rich, throttle full forward. Nosewheel off at 55, climb out at 70-80 (I normally climb out around 80, more cooling for the engine and cover more gorund faster), leave it like that until at cruise altitude, then pull back the throttle and the mixture.
Navajo takeoff: Cowl flaps open, mixture rich, props full forward, throttles full forward (6 knobs!), nosewheel off at whatever speed (I can't remember), pull of at... now I can't remember the name of that V. Positive rate of climb established, gear up, pull back throttles to 35 inches and props to 2400 RPM for climb until at cruise altitude, then throttles to 30 inches, props to 2200 RPM, mixtures to 1450F EGT (that's what my insructor does, anyway), cowl flaps closed for cruise.
I'm sure I missed some steps in there, but you get the idea. That's the kind of stuff I love. I can't wait to start having my instructor kill engines on me right after takeoff and then give me an engine failure on an ILS while making me operate the deice equipment. But I suppose my definition of "fun" is a lot different than most people's...
Sure, I can't do aerobatics in a twin, but that's alright. I'm crazy in wanting to be able to do the other stuff, too. Maneuverability/handling is only one thing that makes flying fun. There are so many others, too.
