This. Definitely this. I'm not saying that DR is a bad game, but it's primary appeal is that it has a board, and some people finding moving around a board more immersive. However, this is very easy to learn (especially if you use the really handy player aid file) and has tons of variety and replayability. DR gives you lots of chances to roll dice, but if you want to provided with different and interesting choices CC has tons of variety in the encounter system that DR just can't match. Especially once you start mixing in the expansions, you never know how a game of CC is going to go and no two games are quite alike.
I find it funny that you as this question in the topic forum, as opposed to the general forum. Of course the people here are going to say to get CC since they're fans of the game or else they wouldnt be here
I say get both but pick DR first. It's a standalone game, with no expansions YET, and you can play it solo when your friends are not available. It is also very easy to learn IMO
CC has two or three expansions and if you're like me, you'll want to get those as well if you like the game.
I say find a video online for reviews and GAMEPLAY and judge for yourself so you won't regret your decision later
