I prefer regular comics pages for myself mainly because everything I do is intended for print first and foremost. But when I did a featured comic for webtoon I just spliced up my regular comic pages into a vertical format comic so I could keep it to print later.
I also do strips and it’s worth noting that certain things do better in different settings. Strips may not do as well on webtoon but there are more strips that have follower counts in the millions other places on the internet (like Instagram and Twitter) than there are long form stories on webtoons with subs in the millions.
I’m pretty sure the biggest comics right now are strips.
