Java's verbosity makes me want to puke. Go wins over java on this point alone. I wish go had generics, but, overall, I enjoy writing Go, because I can do most of the things I did in java while feeling like I am writing python.
I like other languages like Haskell (haven't looked at Rust), but I can't use it on the projects for a variety of reasons.
Modern Java (e.g. 8+) would seem to be much less verbose than Go, as well as being more type safe, once you take the if (err != nil) boilerplate that seems to infest all Go code into account.
If you didn't do any Java for 10 years then maybe Go looks good in comparison, but I don't see how with the modern stuff, especially when you compare IDEs, debuggers, profilers and other tools.
But if you want something much more concise than Java, look at Kotlin or Scala.
I tried Scala and Akka. And then I found Go Concurrency. And then I decided to stick to Go. Scala and Java 8 are probably better, but the simplicity that Go brings in can not be compared to.
