> over pip

It's a much more complete tool than pip. If you've used poetry, or (in other languages) cargo, bundler, maven, then it's like that (and faster than poetry).

If you haven't, in addition to installing dependencies it will manage and lock their versions (no requirements.txt, and much more robust), look after the environment (no venv step), hold your hand creating projects, and probably other things.

Edit to add: the one thing it won't do is replace conda et al, nor is it intended to.
