Dukes vs Kookaburra

The game of cricket heavily depends on the quality and characteristics of the ball used during a match. Alongside the skill levels of players, the properties of the ball significantly influence the gameplay and ultimately, the outcome of the match. In the modern age of cricket, only two types of balls are used at the international level: the English Dukes ball and the Australian Kookaburra Turf ball. There has always been a question in the game about which of these two balls is better for swing bowling. It is commonly stated in the cricketing world that the Dukes ball swings further. Is that the case? Or is that just some English nonsense the poms stand by?
