Github is awash with people's dotfiles including fully featured DEs built on top of things like Hyprland and Noctalia, and they don't require you to use a mess of a distro to use them.
No need to use a whole distribution with 1000 other poor decisions made for you.
I used Vim for a decade (and Linux for much of that time) and the constant tweaking and changing things drives you mad after a while. The more you invent it yourself the more it changes. This is why I prefer MacOS+VSCode these days, which comes with good defaults and simpler VIM-style bindings.
Omarchy sounds like those popular vim configs such as https://astronvim.com/, which I also tried using and also ended up heavily customizing myself. It provided some nice defaults as a baseline but was ultimately comes with too much hyper-customization (which has a lot to do with vim/neovim trying to act like other more modern editors).
