Battlefield bc2 vs black ops?

I mean bfbc2 is such a good game that actually requires teamwork to win, and it is more realistic to me since everything is destroyable, and black ops is faster but it gets boring easily, all they did is recycle modern warfare 2, its the same thing over and over again, another thing that annoys me about c.o.d is that they will ripoff all their fans once again with the overpriced map packs. Ea knows how to treat its customers by giving out 4 free new maps, while the overhyped black ops just made 1 billion$ is still going to ripoff customers and get even richer. I have a feeling that battlefield 3 thats coming out next year is going to be pretty big
