K series will never be the new B series only because of its roots. The B series got us to where we are today, think about it. The K is just the newest thing. The K series is a beast but its on its own level. You cant really compare any of the series motors to eachother they each have something unique. Like different strokes for different folks well everyone has a preference as to what they want. I love the B and its not because I cant afford a K, its just something I want.
