There's enough stories out there that rape the Alien canon hard enough to Predators superior combatants to Aliens.
It's not only a trivialisation of the creature itself, but of the Alien movies that we get emotionally invested in. Every time a Predator mops the floor with a dozen Aliens, I feel a pang of regret that some half-assed comic book writer is inadvertently invalidating Ripley's struggles.
