I don't have any experience in neither Vim, nor Emacs. Should I try it? Looks awesome.
Also - is there any way to add Go (golang) support?
The main problem is customization. Even though Emacs Lisp and the Emacs ecosystem allows for a more organized and advanced setup, there are so many options to do any single thing.
Add to that the newbie-unfriendly documentation, you end up spending way too much time trying to understand how to customize things properly, or at all. Whereas with Vim, if I had a simple customization idea, I would just google it, find a solution in 2 minutes and slap a few more lines in my 1k LoC .vimrc.
You can launch an evil-tutor to start with Vim key bindings by pressing `SPC h T`.
