They're both good. My open source repos are on Github. My private (thus client-related) repos are on BitBucket. I've been pretty happy with this configuration.

Perhaps it helps that I know a few other companies and developers locally using BitBucket for private repos.

Incidentally, reliability and price are both valid reasons to "use an also-ran copycat", in my personal opinion, if that also-ran copycat is pretty damn good.
