Well its quite obvious that the 1515 1.5D would win out in power because it is a bigger motor internally and equivalently a lower wind. A fair test would be your T8 against the 1512 1Y, which is the most simliar of the neu motors, and in fact, pretty identical internally. But just wait until the stiff wires on the Neu fatigue and cause a short, or dirt eventually gets into the holes. Those are two things you will not have to have to worry about or deal with/prevent with the tekin.
