Yarn has been noticeably faster than npm for installing dependencies, especially with proper caching, which has sped up both local development and CI/CD build times across our Node.js projects. The lockfile approach ensures consistent installs across different environments, avoiding the "works on my machine" issues that used to come up with dependency mismatches. Workspaces support has made managing related packages within a monorepo straightforward, and the CLI itself feels clean and intuitive to work with. Being free and open-source keeps costs at zero regardless of project scale, and community support combined with solid documentation means troubleshooting rarely takes long.

Yarn CLI is also fantastic, with simple commands that are easy to remember. Yarn is the most convenient package management in projects, and I believe that security has really improved with version 6!

Very fast, easy installation, and I can manage all my npm packages
