I was excited to start using Ruff however it has quite a few ruff edges for me to use professionally. Back to pylint for now, but looking forward to adopting it once it's ready. The difference in speed was night and day.

Another feature I hope to see in Ruff is to "score" the code. With pylint, I can have a CI rule to make the lint check pass if it scores 8/10 or above, or even a lower score so that co-workers who resent using linters can start using them.
