I think it's worth considering your format and they way you will tell the story. For example, our comic would not do as well if we only published 5 or 6 panels a day. In fact it'd outright SUCK.
Other comics, like slice of life, can do well with daily because the small chunks are entertaining on their own.
It's also worth considering sites like webtoon reward those that update less often by how their system works- so that effects things.
