I like http://beanstalkapp.com/ myself, pretty comparable to BitBucket.
Then again, Github and Bitbucket routinely have the same issue as far as my experiences go (I mostly use Bitbucket, but routinely interact with github due to the project on there)
Beanstalk's web interface had fewer features and, more worryingly, it just failed to display changesets quite often (was also down for maintenance relatively frequently).
