I have about 50 hours in a 150/152 and about 50 in a tomahawk.
If anything I prefer the tomahawk, I loved the lookout, the roomier cockpit and it felt like more fun to fly (I also greased more landings in a tomahawk, but that is probably due more to the last 50 hours were tomahawk rather than the first 50). The downsides as have been pointed out, the trim was horrible to move could move it and after a while would hear a twang type noise in one of them!! The carb heat always used to leave some of my knuckle skin on the instrument panel (always stiff). I didn't like that I couldn't inspect the tailplane properly on a pre flight.
Stuff tends to move around on an aircraft all the time, wing flutter, fuselage torsion, the moving tailplane didn't really trouble me when I saw it as I had read all about the issues involved and was confident of the corrective action in the design.
With the cessna, I never liked having to climb up the engine cowl to inspect my fuel tank contents, especially when the handy little step had been removed, I found the windows on the cessnas I flew tended to pop open upon application of full throttle, the handling just seemed very bland it never felt as much fun even in the aerobat, and I don't like sitting shoulder to shoulder with my passenger, not forgetting occasionally clouting my head on the pitot tube.
But if offered a flight in either one right now I wouldn't turn it down.
