What do you guys consider to be a good ACT writing score? I took it recently and got a 10 and am not sure how to interpret that or whether or not I should take the essay again.
The common data set Princeton has the 25-75 percentiles of the ACT essay as 6-10. I think you are just fine!

I got an 11 for the writing section and a 35 for the composite.
The average writing score is a 7 (scored from 2-12). I think a 10 is really good! Only retake it if you need a certain score for a college. But I think you will be fine.
