I started with Spacemacs. Switched to Doom. Switched to my own vanilla emacs for a year or two then went back to Doom.

I find Doom's defaults well thought out. It just works (insofar as Emacs just works). It has sane default bindings and I can just use emacs to get my job done. There's nothing inherently noble about rolling your own config or choosing a particular kit. Just try them out and see which you enjoy.
