I use both doom emacs and neovim, and I'd say: not really, at least not for me, there are some Vim features evil doesn't emulate properly, or at least it doesn't work like in Vim. Off the top of my head, I write in many languages, but absolutely hate the US international keyboard for accented characters, guess what? Vim has built-in support for digraph[0] by using Ctrl-k and iirc this is a motion keyboard shortcut in emacs, and since I like and use org-mode a lot, I'm always frustrated when I have to type in another language. Another one was with the various Terminal emulators packages in emacs, although this one was solved recently[1], whereas in (neo)vim it works flawlessly ootb.
It's defined in Evil (which Doom uses directly).
Seems like you just need to figure out your bug.
Fwiw use-package is pretty magic and reliable these days.
Compared to Spacemacs, which has complex abstraction layers over Emacs, Doom seems to be much lighter. It's easy to get into Emacs browsing Doom's modules. Plus, the BDFL model is serving Doom quite well since Henrik is a god-tier BDFL. He's constantly active and keeps Doom very focused on performance with sensible defaults and consistent programming style. Docs are a focus and are growing, and they're extremely comfortable to browse in Doom Emacs itself, as well as the Doom and Emacs source code of course.
None of this is meant to attack Spacemacs, it did and does much for Emacs, and many swear by it. But I would say Doom is better these days.
Seriously, check out Doom, whether you use neovim, Emacs, VS Code, or nano (Doom has quite good Emacs and CUA bindings as well). It’s brilliant to the point where I’d describe it as Emacs with sane defaults. I guess it probably can’t match the more niche IDE features but LSP and friends are bridging most of the gaps.
You can finally safely ignore claims that beginners should roll their own emacs configs thanks to Doom. That strategy is good for learning if you’re used to diving into unfamiliar systems but you can learn just as much by starting with Doom and working your way inward anyway. The community is great, just like the larger emacs community.
I can’t stress Doom enough; it gets better often not by the day but by the hour. Henrik is a machine.
