You make a great suggestion. Not that B-schools get everything right or that they're on the cutting edge but, to the degree curricula and lectures are online, I'd probably lean that way more than bestselling business titles. (Which, truth be told, often have a chapter or two that distills down a lot of the key content. In some cases, they're worth the lengthier read to reinforce the key content but often they're not.)
I find lectures much better than books. A lot more engaging and good lecturers are also good storytellers.
Especially if you watch lectures at 2x the speed, you can save A LOT of time. And I'd bet your understanding is better, since lecturers can think through problems out loud. Indispensable, IMO.
I sort of hate doing the 2x thing but I agree with your broader point. My good lecturers were, as you say, good storytellers. Including the guy who won the (I know not really before some pedant corrects me) Nobel Prize for behavioral economics.
