Tua fought many of the best boxers of his era and challenged once for the unified world heavyweight title against Lennox Lewis in 2000.
Nicknamed the ' Tuamanator', his fast-paced bob and weave pressure fighting style has often drawn comparisons to Mike Tyson. In a 2003 article by The Ring magazine, Tua was ranked 48th on a list of 100 greatest punchers of all time. Tua ended his career with a knockout-to-win ratio of 82.6%. He was ranked by BoxRec in the world's top 10 heavyweights from 1996 to 2003, reaching his highest ranking of No.3 in 1998. He scored sixteen wins by knockout in the first round, which included knockouts of world heavyweight champions John Ruiz and Michael Moorer within thirty seconds of the first round, as well as late stoppages of world champions Oleg Maskaev and Hasim Rahman. A highly ranked heavyweight contender for most of his career, Tua was known for his formidable punching power, especially in his devastating left hook.
