I also tried it and am now using it for new projects. But I was just fine with Poetry too. Yes, uv is faster and probably better code. But my use-cases didn't necessitate to re-create the venvs frequently, so the slowness of Poetry didn't matter that much to me, and I am not using the "one-off script" kind of approaches that uv enables (writing the dependencies in a comment in the script itself).
So, yeah, uv is nice, but for me didn't fundamentally change that much.
