@-ShanhaiJing In my experience it definitely depends on the book i'm reading. If it is emotional--tense-- and wrecking--I want scenes long enough to feel complete, short enough that I don't combust.
If it's lighthearted or fast paced story, i'd want shorter chapters.
However, the frequency of updates plays a part as well. If the updates are once a month--or longer--I'd expect or hope for, a longer chapter. If the updates are weekly or more than that--I'd be okay with shorter chapters.
