The "Aggressive development" point is what got me to switch to VSCode from Sublime. While most of my colleagues were switching to VSCode, I stuck with Sublime, after never fully jumping into Atom for performance reasons. However - and I'm assuming due to the open source nature of the platform, or the accessibility of JS vs Python, extensions were just higher quality on VSCode. I think the Go extension is maintained by Microsoft themselves. Very soon things just worked better in VSCode.
