A strong 8 by me. It was truly a shame that Booker didn't become WWE champion (yeahhh I know dude was World Heavyweight champion). His charisma was top notch, his promos were satisfying, and his matches were average to pretty good (Booker/Benoit best of 7). Dude held the WCW on his back during the final years of the promotion, only to get shyt on in the WWE for a few years. Hell, every crappy gimmick and storyline they threw at Booker, he ended up turning into gold. Booker/Goldust, King Bookah, and even his commentary was all greatness.
Bottom line, Booker T should be mentioned with the GOATs when wrestling is discussed.
