Pardon my intrusion, but let me give a fresh perspective:
No systems (boxing, asian martial arts, etc.) will guarantee you to be the best fighter.
The systems only provide you with their accumulate experiences on the training and fighting methods.
Some people grasp them well, some don't.
How do you compare an apple with an orange?
One way to do it is from the content of their vitamin C
So, which one has more vitamin C? Apple or orange?
It all depends on each individual fruit.
Even if (lets say) apples have more vitamin C in average, some oranges (lets say) can have more vitamin C than some apples.
You can't deviate the statistics.
Studying how to fight is studying your own body. You learn about your own body and learn about its strenghts and weaknesses.
Again, systems don't matter. When you are good, you are good. As long as you get the job done.
Just train harder and smarter. One minute you spend here speculating is one minute you are NOT spending for your training.
Good luck.
