HTTP2 is more secure as it uses binary protocol instead of plaintext. HTTP/2 allows the user to have a better web experience by reducing the page load time considerably. It needs the header to be sent just once in binary codes to increase speed.

Does gRPC use only HTTP2?
It’s impossible to directly call a gRPC service from a browser today. gRPC heavily uses HTTP/2 features and no browser provides the level of control required over web requests to support a gRPC client. For example, browsers do not allow a caller to require that HTTP/2 be used, or provide access to underlying HTTP/2 frames.
What is and how works HTTP2 protocol?
HTTP/2 is a binary protocol, as opposed to HTTP 1.1 that is plain text. h2 is HTTP/2 over TLS (protocol negotiation via ALPN). h2c is HTTP/2 over TCP. A frame is the smallest unit of communication within an HTTP/2 connection, consisting of a header and a variable-length sequence of octets structured according to the frame type.
