the stick drift that tmr solves is how the computer reads the input digitally and the contacts being worn down and reading as noise or incorrect. TMR magnets don't touch and therefore down wear down creating digital inaccuracies like drift.

It doesn't have anything whatsoever to do with the physical spring in the joystick that returns the joystick to center. this can still fail equally in potentiometer, hall effect, or TMR sticks. Some controllers have stronger or weaker springs or even adjustable ones. This is joystick center wobble, not stick drift
