I would overwhelmingly say "yes" to your question.
Due to the gear-driven, forced rotation AND forced oscillation, you can definitely buff out a car or boat faster and I'm talking both show car work and production work.
I teach a class on this at Mobil Tech, that is detailing faster using the Flex 3401 to increase profits.
I would also strongly recommend adding the 4" LC baking plate and getting into both 6.5" and 5" Hybrid pads.

2:00-2:45pm Tips & Techniques For Using The Flex 3401
The Flex 3401 is unique in the world of polishers in that it uses a direct drive action to maintain pad rotation without the risk of burning paint or instilling swirls. Learn how to use a Flex 3401 to restore a factory new, swirl free finish faster than using a DA Polisher and without the risks associated with a rotary buffer.
So three years in a row I've taught a class on the Flex 3401 at MTE with a focus on doing pro quality work faster.
