In my experience flying octa vs quad, the octa definitely outperforms the quad. This was some time ago and DJI has made improvements in leaps and bounds to something like 30mins for a Mavic now? But back then, the octa easily had longer flights as it had larger capacity which was filled by larger batteries. It was also easier to fly/handle. Essentially, I'm just repeating/agreeing with everything they said on pages 11&12.
