If you have a smaller codebase which has had consistent good practices you won't find many things anyway. I have a legacy codebase where ruff finds over 25,000 issues. Many times when I fix all of the issues for a given code (say UP031 just to pick an example) I can then run flake8 and find more valid examples of that same issue. On my desktop running flake8 takes about 7s, so there's literally no reason for me to bother with ruff if it is going to be so much less reliable, even if it is 1000x faster. Ruff is ok I guess if you barely need it, but I have a medium sized (about 400kloc), quite old, and extremely poorly managed codebase that I support which powers a profitable business. Ruff just can't cope with it, at least as of a few months ago.
