Spacemacs is indeed great, I used it myself recently. But I will say, it's no longer really actively maintained. The community has migrated over to ~~Spacemacs~ Dooom Emacs, which is very similar (still uses space as leader key and vim bindings everywhere). In my experience, Doom Emacs runs a lot faster too.

edit: Changeed Spacemacs to Doom Emacs, whoops.
