An approach in turbulent air with a gusty crosswind may make the use of partial flaps preferable. The reasons for this are than with less than full flap the aircraft will require less of a change of pitch to establish the correct landing attitude.
I agree with the assertion that partial flaps can be preferable, but I don't think that's a good reason. I'm not even sure that it's true -- it looks to me as if in general it requires a
smaller change in AOA to provide the same change in speed with full flap. It's all very well claiming, as it does elsewhere in the answer, that the touchdown should be made in a "level flight attitude", but if you touchdown while still at flying speed, it's going to get interesting in many aircraft.
My understanding was always that some aircraft had better aileron authority with only partial flap.
