CT has an orchestral undertone. It uses (apart from some synthetic sounds) orchestral samples, just like Alexander btw, and it has 1:1 sync with the scenes. That's where CT and BR differ. BR doesn't have an orchestral tone nor is it this typical 1:1 sync music, though in my opinion there certainly is synchronization going on, but on more abstract levels.
Aside from that, CT has synths from the mid 90's, BR has synths from the late 70's. This is a difference between the two. And whether you like it or not, it's exactly these late 70's synths that emphasize the distance that the BR future imposes.
