I'm about halfway toward a PPL myself and have been trying to practice with a simulator. My biggest complaint is that control inputs seem to be almost completely different from the real thing. Maybe it's the hardware I'm using, maybe it's my own lack of experience, probably some combination of the two... but it's been a mixed bag for me, largely due to the controller situation.

For example, I explicitly stopped using a supposedly more realistic yoke controller in favor of a HOTAS joystick because I repeatedly found that I just _can't_ translate the physical inputs to a real plane. Yoke controllers in particular seem hard to get right (or maybe mine is just bad), but more generally, PC controller axes have a surprisingly low resolution (just 256 steps on an axis) making them wildly less precise than real thing, plus there's no force feedback. Using a completely different (and more precise) type of controller seems to help keep my brain from drawing conclusions it shouldn't.

Simulators _do_ seem helpful for more abstract stuff, like going through checklists, practicing maneuvers, experimenting... so long as you're very intentional about what you're trying to learn. I think I benefited some from practicing ground reference maneuvers [0] in X-Plane with a VR headset, for example, since they're largely visual and aren't tightly tied to physical inputs. On the other hand, practicing stalls in the simulator has probably lost me a decent amount of time in the air with my CFI trying to un-learn the wrong ideas I picked up, due to both control differences and (I think) simulation differences.
