I guess I'm the odd man out...
I like the AvP Elder better. The P2 Elder looks more tribal yes, but he looks young and too much like a normal warrior Yautja, not enough of an upgrade. The AvP Elder has heavier armor, the bigger staff, almost like a big King's Cane, and the cape, the long gray hair, he just looks older and more experienced, and more like an upgrade from the warrior preds. He just looks cooler, and more the type.
I'm going with AvP Elder.
