Interesting I like all of your thoughts! I just went by what Tom Woodruff Jr. said about the predators making the AVP aliens more smart, aggressive, and breed fast and also what I saw in the AVP movies. As for the Alien Resurrection guys, I just asumed from their nature of attacking random prey(captain of the Betty, that pore general, and the black dude). Also the fact they learn very fast (figured out the cold switch button, used the cold switch button!, they where so intent on getting out they suicided one of their own to get out).
