Gene Tunney. A beautiful boxer with a great jab, every other important punch, fluid combinations and proficiency with either hand. Gene could also switch to slugger mode and finish off a reeling foe. And his defense was excellent: angles and great footwork. Every young fighter should watch Gene.
The perfect style is the boxer-puncher. Doesn't excel against most types but is lacking in the distinct weaknesses that the other styles have.
