Very subjective. I understand the rite-of-passage impulse to build one's own config. But it is simply too much time/effort investment if you are relatively new. This I say as someone who had my own config for a couple of decades.

When I came across Doom, I threw mine away and just adopted it. I even learned to like VIM/VI style text editing to use Doom effectively.

I also like the GodMode/Leader/Model style of text editing. The keybindings are more intuitive and more discoverable. When I enter a key and wait a bit, doom pops up next available options. I no longer memorize the keybindings. Just use the whichkey integration to find things I use infrequently.

Not to mention that it is well tested with the sets of packages for each release.

Obviously, not for everyone.

But I am a happy user and hope it exists for a long while.
