>>149176062The image size limit is very similar to tapas and webtoon actually, which is why I feel is a tad constrictive.
In terms of readers, I don't have actual numbers of course, but I feel like there's more on the duck, you'll get a lot more people reading on the duck than on tapas even if have more subs and post the exact same comic in both.
But webtoon, yeah no contest, webtoon has a lot more readers, but I feel like webtoon is actively hostile to both reader and creator alike, so I can't recommend it too much either.
