The deadliest would be...

Krav Maga – Israeli self-defense and fighting system.
Combat Sambo – Russian martial art and combat sport.

The toughest for competitive fighting would be MMA.

Everyone's given you the wrong answer!

I'd say the hardest part of marital arts, is the prenup!

It’s easier to tell you the worst, but the best in no particular order…

Wrestling
Muay Thai
Boxing

If it’s on the “do it if you want to improve health and confidence, but not fight”…

Aikido
Taekwondo
Wing Chun

Marine boot camp!
