I'll be interested in what Mariss has to say here. IME things like
this are not so quickly or easily answered. Motor designers have many
choices...

There's more to a torque spec than holding torque. And "more powerful"
can mean different things depending upon WHERE in that torque curve
you need the "power".

Perhaps even Ray Lin will answer?
