There’s a fundamental difference. xGD is about performance and how repeatable it is, while

GD just measures the outcome. A GD of -20 tells you nothing about whether a team’s attack or defence is over/under-performing. One big win can massively distort GD, whereas xGD looks at every shot in every match, which reduces that distortion.
