From my experience, yolov5 is better on classes with less examples compare to yolov8. I cannot really explain it, but my guess are the weights in the loss that heavily favor bbox parameters over the class loss.
Nowadays it is fairly easy to test different architectures, so do the test by yourself, you'll have an answer that will be more precise than what you can find here :)
