CQC consists of moves which can be found in serveral different martial arts. The Boss did call it basic, but that could because at that time it was, or in her eyes it was, no matter all the different teachniques it had.

However, there's nothing special about CQC, just like there's nothing special about Krav Maga. CQC is big and treated godly because it was invented by two legends. Both CQC and Krav Maga aren't the magical: "I touch you with my index finger and you fall down dead" martial arts.

The fighting styles aren't a main factor here. What should be looked at is stuff like strength and endurance, which I believe Big Boss has the edge in.
