Some females say its more painful to get hit in the clitoris and some men say its more painful to get hit in the testicles which one is true im confused?

I don't thing a realistic study of the issue is possible. Neither gender perceives the tested. & could not reliably speak for anyone but hurt their own.

Clitoris is the approximate equivalent of the male glans penis. So comparing it to the testicle is like comparing oranges and apples. Pain is subjective and depends on many factors i.e. force, time etc.
