Make sure you preview any course you are looking at. Make sure you enjoy the teacher. Both sites are good. Neither is better than the other. It boils down to the teacher. Make sure the teacher speaks to you and you enjoy listening and learning from him or her.
Also read the reviews for each course. Especially the bad reviews. You want to see how the instructor answers a bad review. Is he professional and honestly tries to make things right? Or does he blow off a bad review?
