I find the TeamCity backend easily accessible. Users can login to the Linux servers that TeamCity is installed on and perform operations. Also I find the ability to template solutions using the meta runner a good feature as well as the user management feature. There is a display that shows which user made recent changes to a branch on GitHub, including the time the changes were made and the particular agent that ran the job. This is also a very useful feature. The metrics and audit available for projects, pipelines and jobs come in handy when debugging.
