A broadband solution requires a more costly UE implementation for one, but looking beyond the cost, NB-IoT has the unique feature of very narrowband channels, which enables increasing the power-density of received signals. Being able to increase the power density is important for IoT in terrestrial networks to enable a large coverage area was for power-limited UEs. In NTN the link-budget is challenged by the nature of satcom where the distance is even higher so the importance of this NB-IoT is renewed.
