Unless you're installing a new version of python, I have trouble seeing how preceding all the normal command with "uv" can be seen as much of a difference.

It's not that much of a difference, but it is faster, and when you do need to switch pythons, you're already set up. uv also has some different workflows, universal lock files, and the caching is also nice. And the PEP 723 support is cool!

Poetry was a big difference, it was also very slow for me, and so I never picked it up.
