There's a lot of variation in how the vertical scrolling format is used. Some just use it as "one panel at a time" but with a worse UX, while others lean hard into the scrolling format with things like sprawling panels longer than the length of the screen meant to be read while scrolling, among other things. (It's a bit like asking "how well does putting comics on pages work?" Different comics use the medium very differently.)
