Laradock: separate environment for each project or single environment for multiple projects?

Laradock offers two options: (1) separate Docker environment for each project and (2) single Docker environment for all your projects.

What’s the difference between the two setups? Which setup would be recommended if I have two projects that I’m going to deploy onto a single Droplet (Digitalocean), each using a separate domain name?
