Both dependency management and project isolation are available in a standard Python 3 installation, also out of the box, without 3rd party tool dependency - `pip` and `python3 -m venv`. Admittedly, they work slower, but fast enough for me, especially that I do not run these commands every hour.

Only if you need a single Python installation and you never install any tools written in Python.
