If you were as familiar with boxing as you claim to be you would understand that there is actually very little difference in terms of pure power between fighters. You'd know this if you were in the gym where you claim to be. What makes a fighter a good puncher are things such as technique, timing, creativity, disguise, vision, confidence and fitness.
