Until recently I would've said there wasn't at all much difference between Github and Bitbucket (aside from Github being the de facto home for open source).
However, I'd now argue that Github is significantly better value than Bitbucket for projects, rather than code. By that I mean, Bitbucket is just a component in the greater Atlasssian ecosystem, so it's not a huge priority to add and improve upon project management tools, as you're encouraged to use JIRA, Confluence etc. Even simple things like Bitbucket's Markdown README's not supporting HTML (in particular anchors for same page links) makes the project organisation experience a whole lot less polished.
Where Github shine these days is that they offer a pretty cohesive experience for an entire project's management. Code reviews have come a long way, as have issues and pull requests in general. More recently they've added support for Projects, which for the most part is a Trello clone with built-in integration into Github's issue tracker. Free hosting of Jekyll websites, previews and diffs for all sorts of non-text file formats etc. really put Github in front. Combine this all with the recent change to bill per user rather than per repo (which provides huge savings for small teams) and I don't at all see how Bitbucket are supposed to compete.
I still use Trello for management of clients' projects simply because my clients don't care about the code. However, I can definitely see myself transitioning entirely to Github Projects and the Github issue tracker in the near future.
Frankly, Trello did really well out of this deal from Atlassian. I know Trello have a lot of users, but I'm a bit doubtful about their ability to generate significant funds (paid stickers...?) With Github Projects maturing Trello were likely to lose a lot of users from the tech industry. Atlassian and Trello actually seem like a perfect fit, so it's a saving grace for Trello who couldn't have timed the acquisition better.
