I genuinely can’t think of anything the Java standard library is missing, apart from a json parser which is being added.

It’s your preference to prefer one over the other, I prefer Java’s standard library because atleast it has a generic Set data structure in it and C#’s standard library does have a JSON parser.

I don’t think discussions about what is in the standard library really refutes anything about Go being within the same performance profile though.
