I like the reveal more because it gives a sense of something being laid out from the foundation to a complete project view (Like a journey). Rather than just feeling like zooming out of the canvas like the pull through does.
The Reveal for me. For a vintage map product, the space building itself around the map is the moment that justifies the ad, it turns an object into a little piece of theatre. The Pullback is elegant and calm but it explains less. The Reveal gives the product an entrance.
