I would pick A for the story and B for the clarity. The one that shows the product before the first scroll wins, so I would check which hero has a real screenshot above the fold.
Good test, Piet. A real screenshot above the fold is my tiebreaker too, because mood can't show anyone what the product actually does. Story earns the look, clarity earns the scroll.
Same content, different experience. A few thoughtful design choices can completely change how a presentation feels, flows, and communicates. Which version would you choose?
