Which Python Type Checker?

Question

I've worked with Python in the past but never went deep enough to compare the typecheckers. There are several: Pyre, Pyright, Mypy, Pytype.It's unclear which is the best choice. I'd love to hear the take of a seasoned Python developer.

I typically use mypy. It's been around for over a decade, is available in many package repos, and has pretty good integration with vim lint plugins such as ALE (https://github.com/dense-analysis/ale).

I've had best experiences with pyright, i.e. fewer false negatives, reasonable speeds and good error messages.
