I used to manage my dotfiles with stow (xstow actually) and do some simple links. Now I run an Ansible playbook that creates links or copy depending on the files and also install tools on different OSes.
The big benefit is that it can be organized in a modular way with roles and tags, and sensitives files (like my gpg keys...) can be encrypted with the vault.
