Smoother, and sounds better.
(Something like this

I wasn't refering to a reverse-trike. Well, I'd like to see how the CVT in each scooter motor could provide some compensation analogue to the differential effect, or if it would need some other way to do that.

It's not viable to couple both propellers to only one engine in a twin-engined aircraft. However, at least in the Piaggio P180 Avanti the propellers are so close to each other that it may lead to an impression that both propellers could move during single-engine operation.
