Your post here are all rubbish showing that you have no idea about fighting in real world, you are afraid of being whacked, and you dream that learning a certain brand of martial art will save your ass!
It is like a lamer comparing brands of guns, using a particular gun fight video, and jumped to silly conclusion that brand A gun is better than brand B gun, because in that fight got such outcome.
That shows that you don't know guns, and don't know how to use guns, afraid of being shot, and dream to protect yourself, by selecting a brand of gun, and begin to dream that your ass is now safe, that you could shoot anyone before they shot you!
Fucking childish!
As in all fights, it is that particular moment and conditions, and chances (luck) that decided outcome. Nothing much to do with learning a certain brand of martial art nor brand of guns. You can be more conclusive of fighter A is better than B, if you let them fight 10 times, on 10 different days, at 10 different place, otherwise the any single one time match result tells NOTHING.
You let 1 million fighter learn the same brand of martial arts, everyone comes out to different standards, NEVER the same. It depends on the fighters' health, age, psychological condition, hours of practices, resolve etc. NEVER can a single fight decide which martial art brand is better than another, unless you have 10 thousand matches with 20K fighters over many years, then results may be more representative.
Chemistry between fighters are personal chemistry much more than the brand of arts. You could pick 3 fighters to find that A won over B, B won over C, but they are NOT RANKED A-B-C because, C won over A. Because too many factors in combination effects in play. Age, health, speed, body size, weight, skill, mind, weather, venue, psychology, referee, shoes, head gear, gloves, attire all have a part to play. The same 3 fighters, AB&C, on different days, at different places, under different conditions, different weather, different rules, different gears, may come out different results, if you fixed the same 3 AB&C to fight 200 times.
