Lennox is a wonderful choice. Nigel Benn was a totally different fighter in his 30s than he was in his mid-20s. Against Eubank (II), Wharton, Giminez, McClellan and Collins he showed top-drawer skill - bobbing and weaving as well as a prime Joe Frazier, placing punches, body punching, counter punching, shortened up his power shots, was jabbing beautifully (Wharton fight) and being more patient, ducking, slipping.... he looked excellent against Collins with his bobbing, weaving and counter power shots.
Definitely as him winning the world heavyweight title at 34 in 1897 would be the equivalent of winning the title at 44 now let alone winning the light heavyweight title at 42 which would be like winning it now at age 52 the man was a machine:bbb:bbb:bbb:bbb
Marco Antonio Barerra. He because something like Salvador Sanchez after being similar a swarmer puncher. He worked of the jab, counter-punching and defense. Until he met with Pacquaio, thought that Barerra was the best boxer and puncher in boxing.
