The case for John Part
The first player from outside the United Kingdom to win a world championship, and the only man to win world titles in both organisations and beat Phil Taylor in a final to do it. Darth Maple won the BDO title in 1994 as an unheralded Canadian, then crossed to the PDC and won the 2003 world championship by beating Taylor 7-6 in a deciding set — ending an eight-year reign and producing one of the sport's genuine upsets — before adding a third title in 2008. Four world finals in all, from a country with no darts infrastructure to speak of and a transatlantic commute to every tournament. He remains the benchmark for non-European players and the proof that the sport's talent pool was never geographically fixed. His post-playing career as a commentator has made him the most respected analytical voice in the game, and his articulate deconstruction of checkout routes taught a generation of viewers how professionals actually think.
The case for Dennis Priestley
The only player to win a world championship at the first attempt in both organisations. The Menace took the BDO title in 1991, beating Eric Bristow 6-0 in the final on debut, then joined the 1992 breakaway and won the inaugural WDC World Championship in January 1994, beating Phil Taylor 6-1. He reached six world finals in all, losing four of them to Taylor across the late 1990s, and won a Winmau World Masters among more than eight televised majors. Being the second-best player of the Taylor era is a thankless historical position, but Priestley's peak was genuinely close: he was world number one, he won the sport's biggest title in two separate universes, and in an era without Taylor he would plausibly have collected five or six world championships. He continued competing into his sixties, having also fought and beaten prostate cancer during his career.
