Tyranids because they have bioships which enables them to maintain a steady flow of troops( if the situation is that the Tyranids are invading a planet that the Xenomorphs are inhabiting) and can configure their genetic makeup to be able to overcome the xenomorphs. Plus the Tyranids have various forms/types to call upon to combat the Xenomorphs. Overall I'm pretty sure that the Tyranids would win because of overwheming numbers. Also I don't think the "face-huggers' would be any effective against the Tyranids.
