What's the difference between a 'match ball,' 'training ball,' and 'club ball'?

Match balls are thermally bonded with the tightest construction tolerances and the highest price. Training and club balls are usually machine-stitched, more durable on rough surfaces, and significantly cheaper. Reviewers on soccerinnovations.com and r/bootroom repeatedly point to machine-stitched club balls as the best value for everyday kicking around.
