Completed SoTN. What Castlevania game should I play next?

Current Events

Aside from the tedious backtracking and the Inverted Castle, I found the game to very enjoyable. It took me 16 hours to complete. Is it worth going for the 200.6%? How are the modes with Maria and Richter? Ive read that improves Aria of Sorrow improves on a lot of things SoTn did. Should I go for Aria next, or should I go for one of older Castlevania games, such as the ones on the NES?
