Ranked in these QuestionsQuestion Ranking
Pro Nice and usable UI
GitHub's UI is clean and intuitive. Each view is designed to not fill the screen with useless information.
For example, the repository view displays only the most crucial data about that repo - on the top it displays the number of commits, branches, releases and contributors. When clicked, each of them will take the user to a page that displays more detailed information.
Pro Support for various cloud hosting platforms
GitHub enterprise is available for Amazon AWS, VMware and now on OpenStack KVM as well.
This facilitates the use of GitHub Enterprise for people already familiar with these platforms and allows teams to keep using their infrastructure of choice.

When linked to JIRA, branches, commit messages and pull requests can all reference JIRA issues. This allows JIRA to display information about your development activity in the corresponding issue.
Pro Powerful search functionality
GitHub Enterprise has powerful search features that allow users to search by file name or project name. It's one of GitHub's most powerful tools.

GitHub has improved the LDAP performance. By optimizing searching strategies, they have reduced significant network IO and total queries. Therefore, in some cases as much as 40 percent less data is transmitted on sign on.

Gists are ways to share code or have conversations about anything without needing a full git repo, and still, they work as git repos so they are versioned, forkable and usable from git.

Con No Continuous Integration packaged into the software
You'll have to set up Jenkins or pay for CircleCI, Travis, etc. in order to get CI running alongside GitHub Enterprise.
Con Update cycle lags behind public github
This is intentional, could be seen as advantageous.
Con Can't natively manage large files and binaries (yet)
Max file size limited to 100MB. Git Large File Storage (GLFS) is in the works, but not ready yet. No other native options for large file/binary management.
Con For someone who likes formality, this is not for you
Has slang, sarcasm, and other informal things. If you need to stay formal you shouldn't use this. Personally I like it but others may have different opinion.
Con Difficult to configure
Compared to a solution like Bitbucket Server (granted Phabricator offers more options), it is difficult to configure. Settings are scattered everywhere and you must drill down through several screens to find some of them. Documentation is very complete but also not always in parity with the application itself.
