Basically it makes "average joe" a better driver...
Its easier to push the car and a lot more consistent when you do, best bet is to try one really and see if you like it... Ive always been a Losi man so while the X6 is a good car, it wasn't my cup of tea...
People will tell you to get whichever car they own, best thing is to ask around and try everything you can...
CR2 gets my vote and ive tried and X6, Cougar, B4 etc etc...
