Easy-hosts, ez-config, snowfall... what do you use?

Hello.
I’m looking for a framework to organize my dotfiles.
Currently I’m using just flake-parts, and I have a neat mess that It’s probably not going to work in any other host but my current laptop :sweat_smile:

I saw that there are several “frameworks” for handling several hosts using several Oses, and I was trying to decide which one to pick, but I’m a total noob, and also I don’t have much free time, so porting my current config is probably something I’m gonna do just once.

Which one has the most wide base of users, and why people pick it?
I saw ez-config, easy-hosts, snowball, Nixverse, nixos-unified… and I’m kind confused on what each is aiming for.

One cool thing I would like to have is a one-line install command, so each time a spin up a new server I can just one command and have everything setup. I just recently read something about creating isos from your nix config, so maybe that could be a neat feature to quickly span virtual machines on proxmox.

This gets a bit tricky knowing that I want it to perform an interactive second step asking for a password to unblock my bitwarden vault and extract an ssh key used to decode the secrets, but that is a topic for the future.

Thanks for your guidance.
