If you want popularity and find it easy to write bite-sized chapters, I recommend going for it. That kind of writing has an easier time bringing in the views(if your writing is good enough, of course - but even if it isn't, you should still write and keep on creating stories, since that's the only way to become better). However, if your prefered medias lean towards longer chapter sizes(epic fantasy books, fantasy in general, etc.), then I recommend writing as long chapters as (you feel) is necessary.
That's my two pieces of advice. Please stay around for other people's opinions, as they (no doubt) have much to add to my short exposition.
