It makes it insofar better to me that you have the option to change it. You can’t change Mozilla programs to use anything but .mozilla (apart from modifying the source code of course) so for me seeing the folder is at least a way of telling me that the variable is unset.
The better question is which folder is suited the best to store the stuff that goes into $GOPATH
That doesn’t make it better.

Just because something is worse, doesn’t make the other thing good. A sane and standard default, as others have mentioned, is a small bar to meet.
