Pretty much. In this case, WebSockets is simpler to implement than HTTP2; it's closer to raw TCP, you just send and receive raw packets... It's objectively simpler, more efficient and more flexible.
It's a tough sell to convince me that a protocol which was designed primarily for resource transfer via a strict, stateless request-response mode of interaction, with server push tacked on top as an afterthought is simpler than something which was built from the ground up to be bidirectional.
