Jones fought Tarver again and credit is given. However, Tarver wasn't about to let him alone, there wasn't much else for him to do at the time, and I think he did want to salvage some legacy given the criticism that has been attached to him since the mid 90s. Head-to-head: I'd agree with you. That is where Jones shines in 3 divisions.
Ali, based on how he could figure a way to beat so many outstanding fighters. Jones may have been technically more versatile, but Ali more accomplished strategist.
