Which python package manager should I use?

From https://news.ycombinator.com/item?id=39249005 I found this handy diagram.

Not shown here is pixi which I've begun using on AI/ML research projects. However, its been a pain when wanting to get a prototype app out the door (nowhere near the support on cloud platforms like aws, fly.io, etc. And docker wrappers take some work) and I've migrated to uv on small, shareable projects.

pixi is useful for its comprehensive opinions and toolkits for python version, environment, package & project management, but the ux suffers due to this scope.
