Our experience with BitBucket in the Netherlands has been that it's slow, almost as bad as Jira. I also found the ways things like the PR interface and Markdown support etc to be lackluster with third party support for things like semantic-release lacking and painful. We haven't been affected by Github outages in the last 5 or so years that we've switched to that, so I'm happy we did.
TL;DR: Perhaps the levels of service vary per region?
