I use my GC controller.
For hedgehog stages, Sonic doesn't go exactly where you point. Because he runs too fast or whatever. But even completely stopped, if you want to turn around you have to do it like a tank. Even the super speed sections of Sonic 06 were more responsive.
In werehog stages, the same applies when boosting. And while either walking or boosting, controls during jumps are more akin to Super Mario Bros. 1 (not good for 3D), where you keep your direction during jumps, moving the joystick in another direction only slightly changes it as Werehog Sonic painfully turns on himself and maybe grabs the ledge of the new platform you were aiming for with his nose before falling to his doom. Doesn't help that you're going so slow. Sometimes he won't even jump at all, and you'll walk straight into a pit.
The stiffness of the Sonic 06 controls are also still there, only made 10 times worse by all the above. Just move slight the joystick and you'll move 3 feet forward. What happened to being able to just move half a step if you felt like it?
