There is still strong mutual coupling in the near field if the coils are mutually resonant. The magnetic systems uses a ferrite core to concentrate the field, and these need to be well aligned to achieve high efficiency. These are ferrite based:

The near field systems rely on both coils being within about one radius of one another, and the coils are typically self resonant, but the smaller you make the coil, the higher it's self resonance, thus it's efficiency is lower. That's the issue with resonant near field coupling, the small devices like phones limit the coil size, and efficiency. Near field demo:
