Would expect the variant pulling to ground be slightly cheaper and better as if I remember NPN or N-MOS transistor is if I remember correctly is slightly cheap/better than the P variant, an extra transistor might also be needed. No big deal but it is slightly in wrong direction and usually work equally well pulling downwards.
