I would definitely recommend DoP. Even though it is similar to DC, it has a very different flavor. And I love the books and the lore that's present throughout. I wish DC had more of that.
Try the demo and you can decide for yourself.
BTW, which part of the difficulty curve is getting to be too much in DC? What kind of character are you playing and at what level? I'm interested to know for the purpose of balancing DC.
