Xenforo ftw. I like how Xenforo is more structured and logical; there are a bunch of categories, and within those categories there are threads, ordered by the most recent post within that thread. It was simple and basic, I liked it. I also hate how threads aren't paginated on discourse so you have to scroll through loads (sometimes thousands) of posts to find older messages.
EDIT: However on a scale of how much this issue means to me i'd put it at a 2 or 3 out of 10, I really don't care that much.
