The question is which plugins you used. My neovim configuration gives me "IDE-like features", yet it's noticeably faster than VS Code and others. Also, neovim has native support for LSP too.

It's trivial to switch from uv to other projects like pdm or poetry. uv follows the standard PEPs really closely, so most things are interoperable.

You can use "uv run python script.py" to the same effect.

There was likely something wrong with your configuration. It's really hard to be faster than vanilla vim, but you can get weird performance issues from external plugins sometimes.

uvx is fine. I use it to run executable packages all the time. What is your problem with it?
