Well, I love the traditional page format because I love to have and read physical books. In digital, I still like them, they're familiar and I enjoy them, but I find myself liking to read the scroll format more, because I always use my phone and it's more comfortable to just... scroll and read lol.
When I read webcomics with the traditional format, depending on how the artist does the page, sometimes I can't read the font on my phone, and I have to zoom in. And it's difficult to read like that. In the scroll format the text is bigger, so I don't have that problem.
Reading on my PC is different, because the scroll format seems huge XDD but I almost never read on my PC, only on my phone lol.
Something I really like of the scroll format are the transition panels, artists can be really creative with them! And because the scroll format it's still somewhat new, I think there's still room for experimentation with it, and that's really cool too.
Oh, and I find it more easy to format for scroll webcomics lol. I'm not one of the really creative people that can experiment with it, so I just try to do it in a readable way lol. I use Clip Studio, so it's easier thanks to the program too. Also, I'm bad at paneling for the traditional page format, even though I like it lol I still lack skills in composition so... yeah XD
