Who wins?
By entire, I mean EVERYTHING. Halo, for example, would have all of the Precursors, Forerunners, Covenant, Flood, and Humans all teamed up against ALL the Star Wars universe
They all have their technology as well. Halo has their Halo Rings and such, Star Wars has all their Star Destroyers and Death Stars and all that

The celestials are a tier 0 on the technological achievement scale. They can use neural physics to create universes, life, the force, etc. the rakatans are also a tier 0 species, although in a more early stage, they can use neural physics to invent hyperspace (which trumps slipspace because it's a lot faster. They can also create planets and massive ships too with nothing but the dark side of the force. The old sith empire is a tier 2 species, also with their massive element of surprise and near immortal beings such as vitiate and both emperors wraths they can easily take the halo rings. Also clones, unlike storm troopers, can hit things.
