Third here, it's the easiest tool to setup dotfiles that work on machines ranging from RHEL7 to latest MacOS. Haven't dealt with Windows dotfiles though.
Being able to run `chezmoi diff` and `chezmoi apply` are game changers.
One of chezmoi killer features is how it handles secrets. Either the secret can be encrypted using age/gpg or (super cool) it integrates with you password manager (I used Bitwarden).
This is super useful for me, as I pair chezmoi with dotenv, so when I switch directories, my environment variables are auto populated, including secrets that are pulled directly from my password manager.
