Go wins for simplicity. however what I have seen is companies end up going with Java coz it's simple enough - not simple as Go, but simple enough + fast enough.

though the letdown with Java is the wider ecosystem that makes unwarranted contraptions out of simple things.

Go's big advantage was M:N threads. Java's biggest flaw has been the lack of cooperative multitasking, which people worked around by mangling their code with promises. Now Java has M:N threads too thanks to Project Loom, but there's so much code written before that will never really go away.
