Django is one library that has some apis that are beyond type system and likely difficult to ever fully describe in type system. Some of this it handles with a custom mypy plugin to overrule/extend some type rules. No other python type checker I'm aware of supports plugins so this is one place mypy will have an advantage. Usually when behavior is too dynamic to be described well the stubs will fallback to Any leaving some typing holes for other type checkers.

At same time this only affects a subset of Django behavior and I have used pyright with a Django codebase and it mostly worked well. The more you use very dynamic features of Django the more this matters.

One note for both is you do want to tune configuration settings. Pyright basic is fairly easy to satisfy, pyright strict is too hard for most codebases. Similarly mypy defaults are too lenient, but mypy strict is pretty hard (even mypy doesn't use strict to check itself). I roughly go for strict for both and then remove ~5 hardest rules and call that good enough. Strictest rules pretty much require all of your dependencies to be well typed/stubbed.
