On the off chance that anyone besides me has read any of these, what one did you like the best? Or which one interests you the most (or at all, for you jude them before you read them types)?

I picked Villians United. It really just rocked. The pacing, dialouge, and action was ballanced well, and it really made me care for characters I'd never heard of before at all.

I agree. It brought depth to Villains that needed depth, and showed that not all of the villains are on the level of Lex Luthor

Villains United was definately the best. OMAC was decent and I could take or leave the other two.

I liked Day of Vengance a lot, actually. It's probably my second faveourite, with OMAC a very close third. Rann just didn't do it for me. It didn't really have anything to latch onto and didn't make me care for anyone involved like the others did.
