Topic messaging is best suited for content such as news, weather, or other publicly available information.
Topic messages are optimized for throughput rather than latency. For fast, secure delivery to single devices or small groups of devices, target messages to registration tokens, not topics.
If you need to send messages to multiple devices per user, consider device group messaging for those use cases.
