...YOUR opinion? i know people always say that it depends on the skill level and fighter, not style, but i know there have to be some disparities between different styles no matter what, so which ones do you think are best overall? this is an opinion question
There's differences in action or appearance or tactics, but not a difference in levels of danger or damage. That is my opinion.
I know about seven or so ways to attack someone's eye/s. I would guess, though I can't say for sure, that Keyboard Warrior's jujitsu doesn't include that. That doesn't mean my kung fu is better than his jujitsu, because I'm quite positive he knows certain things that I don't. One is not better than the other, only different. In the end, we'd both put down our enemy probably, we just take different routes to that result.
Most traditional martial arts are dangerous and require significant restraint and control. That is the one real constant.
It depends on your body type. Any kind of grappling is really effective in MMA, but there are striking styles from India and China that are very effective.
