As mentioned in an unrelated thread by another poster, I'm going with Diego Sanchez atop my list.
Who ya got?
Liddell
Couture
Royce
Frye
Wand
Leben
Diaz brothers 
Arturo Gatti. 
Sakuraba
Wanderlei
Shoji
Mino
Jens
Faber
Frankie
These guys always come to fight and none of them know the meaning of the word quit. Sakuraba was thrown to the wolves time and again and more often than not came out of top, and usually managed to do it in entertaining fashhion. Wanderlei is a gladiator in every sense of the word. Shoji was never expected to win, but he took his beatings like a man and never shied away from battle. Nothing needs be said about Jens. Faber would fight on one leg and and with no hands if he had to--he just doesn't stop. Always the smaller man, Frankie is forever bringing the fight to his opponent and is great at persevering through dangerous situations.
Shogun
Any list without Enson Inoue is incomplete IMO.
Igor V. needs to be on every warrior list, imo.
