If your portfolio is only needed to put an URL into a CV so people can see your code, then it doesn't matter. If you want to show that people "liked" and "followed" your repositories, you probably should go to GitHub, just because it has the biggest community. Btw, there is no reason at all to host your git repos at a single site only. I mirror all my public repos between Bitbucket and GitHub.
