I disagree with the title, but it's an okay rundown of the various package managers. Wish the author had tried out hatch though since it seems good. Also rye is not abandoned. You can see the repo has updates within the last 24 hours for a new release. I think they want uv to eat rye, but that hasn't happened yet.

My current favorites are uv + mise. Handles lockfiles, multiple versions of python, and it's very fast since uv is very fast. Have not tried pdm or hatch though.
