Sure! Here is a list of the most important ones (not in any particular order):
- The pull request and code review UI are more user friendly. Everything I need is within reach and clearly visible (build status, test runs, change suggestions, discussions, etc). Gitlab has most of it, but Bitbucket is far behind on this.
- I spend a lot of my "open-source" time on GitHub, so the whole workflow/UI feels super natural to me.
- Issues can track tasks, Discussions can track talking. This is great to keep things organized.
- Great (and simple) release page (recently they added automatic changelog generation from merged PR, which makes it even better).
- GitHub Actions. This is a game changer. It is a well crafted, well documented way of implementing new things in the project workflow. Being able to use a "random" action someone put up that does what I need is priceless. It's like using open-source libs to enhance my code pipeline (allows reusability, discovery, etc). This is also great for CI/CD.
- GitHub projects beta has built-in support for sprints, as well as custom fields (integrated with issues, which is awesome). Everything seems to orbit around the code (imagine coding some custom GitHub action, whose code lives in the same repo as my project, which reacts to the content of a particular issue).
- Issues (and discussions) use markdown and can embed images, videos, spreadsheet, etc, very easily.
