I don't really consider quicklisp to be "great package management" since you have to download it, install it, then load it. And don't forget to modify your sbcl init script to load it automatically for you. It felt quite cumbersome to get started using it, even though it was simple enough after that. Rust has truly great package management in my opinion. I run one command to install Rust and I immediately have access to all crates in crates.io.

EDIT: It's kind of ironic for me to make this claim since I use Emacs as my editor...
