Pyright is much better.

It is much better written, much more correct, has fewer bugs, and it is the default in VSCode so less friction to set up.

In my experience it isn't hugely faster so I wouldn't say that is a big factor. The main benefit is that it is just very correct and has very few bugs (and when there are bugs they are fixed very quickly).

I would avoid Mypy if at all possible. I once tried to fix a bug in it and the codebase was very very hairy. Partly that's because it predates official type hinting support, and partly because it supports a load of hacks to allow incorrect types. Sometimes even the way you write the type affects how it is interpreted (e.g. `a # type: foo` is different to `a: foo`).

The only times I would choose Mypy is if you really need one of those plugins you mentioned, or if you are adding types to a legacy codebase and can't face seeing how bad it really is.
