After viewing the RC a 2nd time, I liked it a lot more this time around and thought it flowed much better. The only addition I still dislike is Mystique going to the mansion, it's not only a pointless scene as they find her anyway, but it also upsets the flow of the 3rd act right when it was gearing up.
I liked all of the other additions this time though and feel they fit the flow of the movie. I am not sure if I prefer it over the theatrical yet but I like this cut a lot more than I did on my first viewing.
