The trouble is, people KEEP saying that. First PoTP was a "mini Masterpiece" (lol I know). Then Siege was a mini Masterpiece. Now Earthrise is. Every Prime we get is the closest to a "definitive" G1 Prime we've gotten yet. Because it's the same design, but because the laws of physics exist and Hasbro has to work under a budget, there's always a flaw that lets the NEXT Prime take the top spot.
