I believe Eubank was the best, Jones' fundamentals were absolutely awful in all honesty. Eubank's fundamentals weren't the best either because he had his own style, and Benn always lacked concentration, but I just feel that Eubank was the most fluid boxer of the three and didn't rely on natural reflexes(Jones) or punching power(Benn). Plus Eubank could clear his head quicker than both of them and Pre-Watson he was the best finisher.
