Ask HN: Node or .net Core or GoLang or any other?

I am working on a side project where i am using React and Redux for the Frontend. In this app/game, I have to maintain the state of the user like (any progress or interaction or last state) as well syncing of the data with the server. So i am in the great dilemma for the server technology selection. I have experience of both Node as well as .Net(day job) but no experience in golang. Can you please suggest, which technology should i go for.
