Right, I think I see what you're getting at.
I used to do semi contact karate and the technique that cleary scored more than any other was the reverse punch.
Lunge punches and backfists seem to rarely score, the same with front and side kicks.
Round kicks to the body were impotent too for that matter, whereas round kicks to the head would often score. The same with reverse round kicks to the head, but not body.
All of the above means pretty much nothing to anyone outside of my old style and the tournaments they entered, as different styles have a different emphasis.
So it's not just about which art it's which style, of which art and very often which association, of which style, of which art.
