Idk, for me ruff was more of a game changer. No more explaining why we need both flake8 and pylint (and isort), no more flake8 plugins... Just one command that does it all.
UV is great but I use it as a more convenient pip+venv. Maybe I'm not using it to it's full potential.
I agree flake8 -> ruff was more of a game changer for me than pip+venv -> uv. I use flake8/ruff for more often than pip/venv.
uv is probably much more of a game changer for beginner python users who just need to install stuff and don't need to lint. So it's a bigger deal for the broader python ecosystem.

You aren't, but that's fine. Everyone has their own idea about how tooling should work and come together, and I happen to be in your camp (from what I can tell). I actively don't want an all-in-one tool to do "project management".
The dependencies descriptor is further structured, a requirements.txt is pretty raw in comparison.
But where it isn't a matter of opinion is, speed. Never met anyone who given then same interface, would prefer a process taking 10x longer to execute.
