Taking COIE off the board since it isn't finished yet, I'd have to say my rankings of the crossovers would be
Crisis on Earth X
Elseworlds
Invasion
World's Finest
And then
Duet
Legends of Today/Legends of Yesterday
Flash vs. Arrow/The Brave and The Bold
I have a feeling that when all is said and done, COIE will be my favorite. As it is, it will be hard to top it.
