FCM is the new version of GCM under the Firebase brand.

Benefits. The new FCM SDK:

1.Simplifies client development. You no longer have to write your own registration or subscription retry logic.

2.Enables a new serverless notifications solution with a web console, Firebase Notifications. With Firebase Notifications, anyone can send notifications to target specific audiences based on Firebase Analytics insights. They can then evaluate notification effectiveness by assessing the built-in Notifications Funnel Analysis in the console.

cons: gives no control for non-data notification when the app is in background — Manza, Dec 08 '16 at 12:49

From Docs

FCM is the new version of GCM under the Firebase brand. It inherits GCM’s core infrastructure to make sure we continue to deliver messages reliably on Android, iOS and Chrome.
