Is Castlevania Portrait of Ruin better than Castlevania Order of Ecclesia

Portrait of Ruin and Order of Ecclesia are relatively similar, as PoR has pictures you have to go into to fight bosses and move through the game by exploring some relatively large sub-maps. OoE has even more places you have to go to get through the game. I was disappointed when I played OoE, because, even though it is fun, a lot of the maps are small, the plot is pretty easy to figure out if you know Castlevania games, and Dracula's castle itself doesn't have many different enemies. Both games have great soundtracks, but PoR just felt like a harder game and has much cooler surprises, so I would say Portrait of Ruin is better than Order of Ecclesia. However, best of them all for the DS is Dawn of Sorrow, if you haven't played that.
