Go back and play some of the maps (pretty much anything but Rust) on MW2.
then play some BO2 and compare the quality, size, and layout of the maps.
You'll quickly find out MW2 maps are MUCH better. It's not even a competition. It's like if someone offered you a brand new Hyundai Accent, or a 4 year old Rolls royce Phantom. Sure the Hyundai might be newer, but you'll find out quickly that the roller is much better in every single way.
