PyInstaller or Nuitka?

Here's a short post for "X":

I've been working with Python for years, and when it comes to compiling Python code into a packaged executable, there are a few options out there. Two popular tools are PyInstaller and Nuitka. I prefer Nuitka for compiling my Python programs because it offers a noticeable speed advantage.

Have you used either? Which one do you prefer? PyInstaller or Nuitka?
