I've been using spacemacs for a while, haven't looked into doom. Mind telling me why you decided to switch?
Reasons:
- DOOM Emacs is fast. Fast to start `emacs --daemon`, fast UX with the default config.
- I've experienced DOOM Emacs to be more cohesive than Spacemacs
I still keep my Spacemacs config around, but I haven't touched it in ... almost a year now.
Additionally, I've found adding my own customizations is much easier in Doom than Spacemacs. While the Spacemacs "layers" approach is nice for setup, it can become very brittle when you start hacking on it yourself. Some of that could also be due to my own lack of skill with elisp, though.
