Maybe I'm just showing my age, but having/requiring a good IDE is a anti-benefit for me. One of the things I'm loving about Go is just how little "environmental baggage" the language has. No Makefiles, superfast builds with automatic discovery of source files, I can continue to use vim for everything, etc.
I personally prefer having the option of popping into an IDE when needed, but do most of my day to day work in Sublime. Everyone has a workflow which works best for them.
