I like it better than Undisputed.
It feels a lot more real. If you play a HW fight, a few hard string of punches puts someone out fast, like it really does. If you play the MW fights, though, it takes a lot more punches to put someone out.
It's a lot more realistic, and I don't have to swirl a joystick around for an hour to pull off a sub.
