Just a few months back I said I would never use uv. I was already used to venv and pip. No need for another tool I thought.

I now use uv for everything Python. The reason for the switch was a shared server where I did not have root and there were all sorts of broken packages/drivers and I needed pytorch. Nothing was working and pip was taking ages. Each user had 10GB of storage allocated and pip's cache was taking up a ton of space & not letting me change the location properly. Switched to uv and everything just worked

If you're still holding out, really just spend 5 minutes trying it out, you won't regret it.

I wonder how it compares with something more green generalist like "mise", to which I migrated after using "ASDF" for some time.

Think of uv more as like npm or other thing like that. The new Python pyproject.toml is similar package.json. It defines the project description, list of dependencies, and other hooks. Uv is a package/project tool using pyproject.toml. It is easy to manage dependencies, build and publish to PyPi, add hooks to run tests, linters, or whatever, again much like package.json. It also manages the virtualenv automatically, though you can manage it yourself.
