Difference between using a Z-score and using C as average to curve exams

I am choosing between 2 professors, one of whom curves his exams by keeping C as average and the other one takes the score you received, subtracts it by the class mean, and divides the whole thing by the standard deviation. Then he uses the number he uses and plugs it into a table to get our final grade. Can someone please help me understand who's system is better and take the best professor because both of them are equally good at teaching.
