Yes. The difference is there is no difference. That is a marketing ploy.
If you choose to duel. Which I do these days. You may still wind up in the pocket trying to work from a bad position. And you need the ability to deal with that.
If you are an instantaneous street fighter and the other guy does this secret street fighting trick called taking a backwards step. Then you need to have the tools to deal with that.
Now I duel because I have developed those skills of timing and entries and footwork. And so can employ them instead of being able to eat punches.
Which if we are talking efficiency is better in the long run.
(And this isn't an either or debate. Having an iron chin and cardio for days. Doesn't mean it still isn't better to move away from punches.)
