I generally don’t mind either of them but I think it is easier to screw up the page version with terrible page layout, making it confusing to read.
On the creative side, for me it’s more a decision to simplify my life on the panel layout side. I use the scroll view to make the planning and production simpler. I don’t have to do a puzzle every time I create a page. Also since I have no plan for a physical version of my comic, the choice to optimize for endless scroll was easy to make.
However I think that choice does limit me in other ways. In page form, it is a lot easier to play with the weight of each panel. Small panel for small action and so on. With the endless scroll format, my comic skews a lot closer to the storyboard with dialogue boxes, which bring its own set of problems like often uninspired panels.
