The problem with the issue tracker on Bitbucket is that it's not getting better because it would 'cannibalise JIRA' sales, but it's ridiculous that in 2015 I still can't create links between issues, or create subtasks. If I had to pay for a better issue tracker that's built-in to Bitbucket (no JIRA), I'd pay it.
The rest of it actually fits my needs although I am a one man army so YMMV.
I haven't tried it myself though.
