As for the stingray, it has its place and I think this be quad will push Curtis into hyping his stingray. Pros of the stingrays, be motor drives the entire quad. So I see that as being a plus. The negative to that is more parts and points of failure while in flight.
This 400 I think is geared towards the beginner or week ended that just wants to fly, whereas the stingray is more for the serious pilot who flies all the time.
Will see how this plays out.
