I just defer to the code formatter. That way everything is consistent looking internally, which is all I care about. I couldn't care less whether the braces are on the same or a different line or other things like that outside of the fact that I do like internal consistency within projects.
All that aside, as soon as I saw the OP title I knew (via years of exposure to bikeshedding programmers) that this thread would end up having a ton of comments on it and wasn't surprised to see it was up to 500-something and still rapidly climbing.
So totally this. I despise indenting with tabs with a passion, but when I heard gofmt did that I was actually pleased. There's no arguing with the official formatting utility: https://golang.org/doc/effective_go.html#formatting
