I'm pretty sure that Jason had said that the Gladiator cover is stronger, grippier than the one on the AMB solid. If that is true (if I remembered correctly), then with the AMB having more flare, depending on the drilling, and the bowler's hand, the AMB could be earlier or later, with more or less backend.
It's very difficult comparing different coverstocks with different cores, even with the same bowler throwing both.
Here's an irony or a sarcasm, depending on how you look at it. The AMB solid is finished 1000 grit. The Gladiator is finished 2000 grit Abralon. Since we've just learned that the grit numbers on Abralon pads are "P" based, that is the European scale, (Someone here verified this by sending an email to Mirka, the manufacturer and designer of Abralon pads.) these 2 balls technically have the same grit level, since "P2000" is equivalent to 1000 grit US scale. Fascinating.
