Pro Auto-fill remembers last user
When a site has multiple credentials (like I have for some brokers and banks), then the most recently used is automatically populated (if auto-fill is opted). This feature is unique (to my knowledge) and spectacular (especially for sites that log you off frequently and re-logging in is required).
Con No native desktop apps
As of September 17, 2017, there are no native desktop apps, although they are due.
