Which one is more reliable for Server sent events Firebase Realtime DB or FCM? : <p>We want to send some realtime server sent events to our client apps so we decided to use Firebase cloud services. Which one is more reliable for sending realtime events Firebase Realtime DB or FCM? 
We need to make a decision because our requirement can be solved in both cases but FCM is free where as Realtime DB is paid. What are the cons If I opt for FCM over Realtime DB?
Thank You</p>
