As a team we need to push code into the repo on daily basis, Bitbucket has proven that is a reliable and secure server to save and get the code available in no time. The administration part is really easy and there's an extra tool for every developer profile either if you want to use the console or a GUI like Sourcetree.
IBM Rational ClearCase might be better suited for a smaller / simpler code base. Larger code bases really slow it down... but then again there are better alternatives out there for source control
Very easy to integrate with other DevOps tools like Jenkins and with project/workflow management tools like JIRA.
Very efficient in managing security and compliance standards for code, especially during pull requests, merge requests, branching, etc.
Very robust in performance, especially the cloud and datacenter versions hardly hit any performance issues and supports more than 2000+ developers in my company.
Rational ClearCase is excellent for handling versioning and branching. No other tool I've used has the depth that ClearCase has when it comes to handling complex branching scenarios and identifying where certain versions of particular files are within a particular configuration.
Rational ClearCase handles parallel development of many dependent applications really well.
The use of ClearCase Views to switch between projects and configurations is extremely convenient as opposed to the local workstation model of the competitors.
All products have room for improvement. The system improves over time with better and better integrations and I look forward to even more features without paying extra! The system has increased transparency across my organization and with this transparency comes increased throughput on projects. I don't think I can go back to any other system and we are definitely married to this product.
The architecture of Bitbucket makes it more easily scalable than other source code management repositories. Also, administration and maintaining the instance is very easy. It integrates with JIRA and other CI/CD applications which makes it more useful to reduce the efforts. It supports multiple plugins and those bring a lot of extra functionality. It increases the overall efficiency and usefulness of Bitbucket.
The customer support provided by Atlassian (Bitbucket's parent company that also makes Jira, Confluence, etc.) is very helpful. They seem to be very concerned about any issues reported with their products and even just questions about functionality. They are constantly improving the products with new features in nearly every release. Plus they have a plethora of online documentation to reference.
For the features we were looking at, Bitbucket, GitHub and GitLab were all at par and were in a similar price range. We found that GitHub was the most full featured should we need to scale very quickly. GitLab was at par with GitHub for our future needs, but GitHub was a more familiar tool compared to GitLab. Bitbucket won out because of its close integration with Jira and being in the Atlassian family. It was also cheaper than GitHub. As we started with Jira, Bitbucket addition became a natural next step for us. We really liked Bitbucket and stayed with it but we do know we have great options in the form of GitHub and GitLab should we need to scale fast.
If development is centrallized to one location and your company releases hundreds of customized versions of your software per year, then ClearCase is the best tool for managing the complexity of multiple versions of customized software. If your company has globally distributed development, then I'd recommend Team Foundation Server over ClearCase. If your organization uses Agile Methodologies, then I'd recommend TFS with GIT.
