RoF has been out (in the wild) for years and CoD hasn't... so of course the RoF is going to have less bugs, and do keep in mind RoF was extremely buggy when first released. (crikey) given the amount of time RoF is in release, it would have been nice to see how the CoD engine would have polished up, given the same opportunity)
