Don't worry 2 much dude - everyone asks this question at first.
The best way to get the answer to that is to search - there'll be LOADS of results and if you have time to sift through most of it, you'll be well educated as best you can based on people opinions.
No one person can give a correct answer, only what they like. I like Revo, but can't say its better than CC because i've never had it on my car so can't compare, and even if i could, what works better on my car may not on yours - so you can see hard it is to answer the question.
Also, get the free trials of both and see how the car FEELS in comparison, that should be the biggest factor, along with customer service from your local dealers.
