I don't have any experience with the nue motors, but Lutach's logic doesn't make sense. If you gear for the same speed with two motors of the same resistance (no matter the kv differences), you would ideally use the same amount of power, but in reality the 1521 is bigger and heavier, and will take more power to run. Lower kvs mean more torque, but once you gear up to match the speed of the higher kv motor, you lose torque at the wheels (thats what counts) and you increase the current. So why would you NEED a 1521 in the first place? So you can run higher voltage without reducing the current for more power. e.g you can run a 1521 1.5D on 6s which is too much for the equivalent 1515 1.5D.
