Pro Multiple authentication methods
BitBucket supports GitHub, Twitter, Facebook, OpenID, Google and even GitHub authentication.
Pro Free private repositories
BitBucket allows users to have free private repositories as long as it's a team smaller than 5 that is working on a project. In other words, BitBucket charges per team member and not per repository member. This feature may make BitBucket, even BitBucket pages better than for example GitHub for some, since the static page's source code won't be open source, but it can still be viewed on the browser, so for static page hosting per se it is not a big deal.
Con The UI seems old and not very polished
While GitHub's UI is extremely simple to understand and very polished, BitBucket lacks a bit on this category. With a design that seems old and not as pleasant to look at.
