I like that it's open source, so there are lots of plugins available for you to use as needed (or not). It also has built-in support for Git/SVN repositories with hooks into GitHub or Bitbucket if your organization uses those services. The UI is very easy to navigate through -- no need to spend time learning how things work! There isn't much functionality in place by default but more can be added using plugin development tools. If we were looking at different options between CI servers then this would definitely have been one consideration because its ease of configuration makes getting started quick without having any issues down the road. Having an automated build process allows us to ensure our codebase stays up to date while keeping track of changes made across multiple developers within my team easily. We're able monitor builds from start until completion via Slack notifications which helps keep everyone informed about what they should.
