From what I hear from several reliable sources, Candra was pretty much in a league of her own regarding her talents.  The queen is dead, long live the queen.

Having said that...I know a couple of people who have seen Terra, and they were quite pleased with her skills.  Her reviews seem to be pretty in sync with what my friends said, so if her "specialities" are what you are looking for, you likely can't go wrong with her.
