What's the difference between ACA and ACL cornhole boards?

r/Cornhole consensus is blunt on this: the ACL (American Cornhole League) is the dominant competitive sanctioning body, and ACL-licensed boards are what serious players target. Multiple specialist-community threads describe ACA-branded gear as recreational rather than truly competitive, so if 'tournament regulation' matters to you, verify the board is ACL-approved, not just labeled regulation-size.
