I think you can ignore the lens motor factor in your purchase decision. Any new lens, Nikon or Canon that you are likely to buy has a motor inside the lens.
That model Nikon cannot autofocus old Nikon lenses (higher spec Nikon bodies like D90 can). OTOH you can't use old Canon lenses anyway because they changed the mount a decade and a bit ago.
So get whichever one you like best
