Truth be told, the only thing I can picture the Xenomorphs having an upper hand is the fact that their blood is acid. As for the drone vs Warrior: Not a chance, a Warrior can take on a Space Marine and don't even seem to feel any pain (An Ultramarine rammed a combat knife in its eye and it didn't even flinch) A queen vs a Hive Tyrant though, there I can agree that the Queen would win.

But then there is one thing the Nids have that no Xenomorph can ever match...

Bio-Titan.
