Xenomorph vs Slither Creature

Battles are won by death. The Slither creature tries to take over a planet with Xenomorphs.(Queen, facehuggers, drones. etc)

Which species lives on.

The fighting goes to the Xenomorphs, but neither live on, as there are no viable hosts for the aliens to impregnate.

Maybe slither would be able to infect the xenomorphs, but not vica-versa, maybe.

Xenomorphs. The Queen would instantly know if one of her kind was infected due to her telepathy and hive mind. The Slither creature would be exterminated before it had the chance to actually spread. Also Xenomorphs by far are the superior creatures. Acidic blood alone would prove fatal for the Slither creature.

Xenomorphs will live on and stomp.
