There is no one paradigm for concurrency, no method is strictly better than the other. Channels are not the only primitive used in go either, so it's a bit moot point.

What's important is how good primitives you have access to. Java has platform and virtual threads now (the latter simplifying a lot of cases where reactive stuff was prevalent before) with proper concurrent data structures.

But that's only because they're older and were around before modern concurrent programming was invented.

In C#, for example, there are multiple ways, but you should generally be using the modern approach of async/Task, which is trivial to learn and used exclusively in examples for years.

What are Javas 2 different paradigms?
