Comparing Go with Java without knowing what area the application should be used is about guessing. I think in every aspects regarding loading time, executing time, footprint - space and memory - and simplicity, Go will be a better choice compared to Java.
I have only worked with some narrow areas. Web development where Go is serving both as backend and a part of the frontend (Go HTML Templates). Better than its reputation IMO. I have also played with API where Go shines and other micro services.
Here a thread which have some good other inputs.
