I think I have a compromise approach. It prevents me from/saves me the effort of having two different sets of habits, and all the things I fly now, even for fun, are complex airplanes. (I'm lazy.)I'm still a proponent of "fly the airplane you're in." I think the methodologies are not mutually exclusive, and that's an important distinction. Habit patterns of "paperwork / numbers flying" a Cessna can kill you in the same manner that 'seat of the pants' flying can kill you in a much larger airplane. (I presume—my direect experience only runs to slightly larger airplanes at the present time.)
As far as "seat of the pants," I assume you're talking about airmanship. Having an innate awareness of the aircraft's energy state and lateral and vertical flight situations/paths is absolutely essential and it doesn't matter what you're flying—you've got to have it. For what it's worth, even the larger aircraft I've flown have a "feel" to them, and they all talk to you. Some of them are more subtle than others.
Your seat of the pants is often right. If the ball is out of the cage, I'm likely to tell because my ass* is having assymmetric force applied to it, even without putting down, uh, my FOM to look at the ball. And so on.
