Ruff is performant but finds about half the issues Pylint does (see https://github.com/astral-sh/ruff/issues/970). Ty is quantitatively the worst of the well-known type checkers (see https://news.ycombinator.com/item?id=47398023). Uv is Astral's only winner.

You are aware that ty has only recently entered beta status?

Ruff isn’t stable yet either and has evolved into the de facto standard for new projects. It has more than double the amount of rules than Pylint does. Also downloaded more than 3 times as often as Pylint in the past month.

Pylint has some advantages, sure, but Ruffs adoption speaks for itself. Pylint is 25 years old. You’d hope they do some things better.

Saying that uv is their only winner is a hilarious take.
