Tough call this one but I went for Nigel Benn as he was just a revelation to watch in my early years of watching the sport. He would also not shy away from a tear up, he was entertaining and is remembered for his offensive style and obviously then there's the Eubank/Collins/Watson fights which really were quite special.
Cooper, for me, is our 3rd best heavyweight ever. He reigned as the best domestically for over 12 years in the greatest era of heavyweight boxing in this country, scored one of the most famous and talked about moments in boxing when he floored Clay, won three Lonsdale belts outright, and had genuine crossover appeal.
Benn is one of my favourites and he achieved plenty himself, but I'm going with Cooper.
You want to decide when a poll is over? That's like playing God! You think you're Charlton Heston, mufucka? Huh? This ain't no burning bush! We ain't no damned, dirty apes! Wait-...ah, never mind. I'm getting confused. Is this poll made of PEOPLE?
