Each airplane is a little different. We tend to gravitate toward that which we know best. I learned to fly in a J-3 cub, and found it more enjoyable and comfortable than most others, at first. Soon I found that the differences are really quite minor, as you'll find given a little time and experience in different airplanes.
Still, when paying the ridiculously high rental fees these days, you're not paying to be uncomfortable...find what works best for you.
If the controls feel a little heavy, try using more rudder or trim. You will find a little difference in the feel between a flying tail and simply moving an elevator, but again, the perceived differences go away quickly.
The 172 is a dirt simple, easy to fly, comfortable small airplane with no bad habits, simple systems, that can be landed about anywhere, flown from about anywhere, and is easy to maintain, good on fuel, has excellent visibility, and exists in larger numbers than nearly any other light airplane...it's a prove design globally. It may not be for everyone.
