So long as I can easily navigate through a site, I don't care where a comic is hosted. Most comics I've seen on blogs can be a pain to follow. call me lazy, but I want to be able to click a button and see the next page, not have to sort through various blog posts, or scroll backwards down a page trying to figure out what goes where.
I started my web comic earlier this month, and have been using Comic Fury to host it, and I really like it so far. It's pretty easy to use, and the forum community is one of the friendlier that I have come across on the internet.
I went about answering this very same question by thinking of myself as a reader. What format do I like, and which comics do I remember the URL to and which do I go "damn I wish I could remember that."
In general I find that I prefer comics hosted on a site dedicated to that comic, but that does not stop me also posting on dA and linking in from my blog and facebook and anywhere else.
In the end what would be easiest for readers? Do you like reading things on ComicFury? Do you like reading them in a blog format? Is it cumbersome will it put readers off if they can't navigate and find your work?
