Really they are apples and oranges. The CC is built much tougher and the NICE frame will carry weight much better then the dragon fly. The ideas are much the same where you can expand the CC to haul but keep it compact like a day pack for spot and stalk.
The CC will also carry a load much better then the eberlestock. I had a J105 and while I liked it it didn't carry a load well at all. It was fine for load less then 30 pounds but after that it felt like I had something pulling at my back. The water proof fabric on the eberle soaks up a lot of water but stays dry on the inside.
There is a big price difference in price between the two. If you could get your hands on a CC to compare I think you would see the difference in price is worth it.
Customer service is top notch on both companies so I would not worry about that.
