IMHO, using spacemacs and doom-emacs (tried both) you're not really trying Emacs because you're using vim shortcuts (that I love, I'm a vim addicted) on top of Emacs infrastructure, nothing bad with this approach, but definitely you're not having an full Emacs experience. I like doom-emacs, do no use it simply because I do not like distribution for text editors (prelude, spacemacs, doom-emacs and so on).
