Using grpc-web should be fine if you don't need the bidi features (streaming writes or watch). In addition to those features, using the web SDK gives you rich offline support (reconnects / retries, offline caching, etc.), latency compensation (the ability to see your local writes immediately without waiting for the network round-trip to reach the backend) and a very friendly API (we abstract away a lot of the complexities of the wire protocol and make it very JS friendly).
