Hi Joe,
Core server features for developers are generally the same, but a MongoDB Enterprise subscription includes additional operational and management features, a commercial license (warranty & indemnification), as well as access to proactive support and on-demand training.
Some specific product additions are: advanced security options (auditing, log redaction, Kerberos, LDAP), additional storage engines (encrypted and in-memory), management tools (Cloud/Ops Manager), MongoDB Connector for BI, and the full version of MongoDB Compass (includes features not in Compass Community edition such as Enterprise authentication support, schema analysis, real time server stats, and document validation).
Regards,
Stennie
