Got up and running with debugging Go code in Emacs in about 2 minutes.
It renders variables inline, as well as when I put my cursor on a variable (eldoc-box).
dape lets me navigate the call stack, it auto expands all local variables, it provides a REPL and more besides.
And all I did was:
# pacman -S delve
M-x dape RET RET
I've yet to try out the more advanced features of delve, like attaching to a running process, but first impressions sure look good!
