My experience is that ruff reimplemented 99% of the most popular features of black, isort, flake8, pylint, etc. and then added 10000% more features on top, that feels like a fair tradeoff to me. I've converted multiple large Python codebases to ruff, and each time I just configure ruff as close to the previous tools as possible, then reformat the entire codebase with ruff and remove all the previous tools. The speed increase when linting alone is worth the minor formatting changes to me. If you really insist on keeping isort's sorting then you could at least replace black and pylint, which would reduce the total number of tools by one.
