Battle of the Brainiacs

All the different variations against each other:

Pre Crisis Brainiac
Milton Fine Brainiac
Doomsday Brainiac
Brainiac 13
True Brainiac
Crime Syndicate Brainiac
Convergence Brainiac

Who wins?

I vote for the one that liked to twirl his mustache like Dick Dastardly...

Or the creepy Cyborg one from the Bronze Age....
