Who were the best ancient martial arts warriors?

Hwa Rang were legendary in their time. It's hard to compare because the tended to be around at different times. Shaolin were the 1st & were outstanding. Hwa Rank Do & Sulsa came next. Samurai & Ninja came later & I don't know about the Yamabushi. I favor Wha Rang & Sulsa, but then I study a Korean Art.
