Depends on what you mean by 'get used to'.
The first person space MMO I played before Elite: Dangerous didn't have the equivalent of an FA-On mode, so I was always used to having to account for drift. After they reduced the rotational damping in Beta 2, I did have to readjust to that and I did so fairly quickly as it was virtually mandatory due to the exposed locations of the Viper's thrusters (this was before they pulled the hit-spheres for the thruster ports, so hits to the front of the Viper's thruster nacelles could induce thruster malfunctions).
Never found FA Off landing or maneuvering to be difficult, but I'm still not used to aiming weapons while FA Off, especially with railguns, though I can manage with PAs, if I have to.
Anyway, I've always found the idea of committing to a given flight assist mode rather bizarre, as each mode has a collection of performance advantages and disadvantages that cannot be entirely replicated with the other mode.
