I have the Ultimate, Real Deal, Thing Lives, Big Bully just saw the Big Deal thrown today. Ultimate is good but does not flip over as hard as the Real Deal. The Thing lives is a little more angular than the Real Deal and harder to control, at least for me. Big Bully is drilled weaker so I can't truely compare it. From what I saw of the Big Deal, it is REALLY angular but you have to KEEP IT IN THE OIL BIG TIME. All of the above are good balls and leaving out the Big Deal, my Real Deal is the most consistant and seems to hit the hardest. just my opinion, may be different for others. Hope this helps
