Women's Hospital has a lot of different classes. We took the breastfeeding, the parenting, and the CPR class - all were well worth it!
I delivered at Women's and was very pleased with my experience overall.
I think it's good to take the childbirth class at the hospital where you will deliver. That way you can learn their policies. Other ones can be more about convenience (I didn't deliver at women's but I took the breastfeeding class there because I'd heard so many good things about it.)
