So who would win in an all out battle? It takes place in our solar system and they have equal numbers and resources. Also, the Gravemind is fully developed. Both also have access to the fallen, cabal, hive, etc. So it's an all out battle to infect/posses as many victims as possible, and defeat the opposing force. The Flood can also (possibly)infect the Vex as their Mind Cores are biological.
