Ruff actually focuses on checks that don’t overlap with Black. (“By default, Ruff enables Flake8's E and F rules. Ruff supports all rules from the F category, and a subset of the E category, omitting those stylistic rules made obsolete by the use of an autoformatter, like Black.”)

Its import sorting is designed to be compatible with isort --profile=black by default (https://beta.ruff.rs/docs/faq/#how-does-ruffs-import-sorting...). Many isort settings are supported (https://beta.ruff.rs/docs/settings/#isort). I’m not sure what “fly to top” means.
