Thor in the films is just too slow for Superman... Considering the time it took for him to call his hammer when fighting Malekith in London... He would have been thrown on another planet if he was fighting Clark instead.
Also, Superman seems more durable. Thor was feeling the burn when he was thrown through boulders, Superman fell from hundreds of feet up when flying and landed into a mountain, hard, and looked more annoyed than injured. Also Thor gets shanked by Loki daggers, I would assume they would shatter if it hit Superman (unless they're enchanted )
Loki's weapons are -always- enchanted. Bullets and other bladed weapons were bouncing off Thor like nerf-guns.
Plus, Thor was feeling the burn because he was going toe-to-toe with other Gods and Godlike beings.
Okay, Riddler dominates round 1, round 2 is closer. I believe Batman and Sherlock have met and I recall them being approximately equal, though Sherlock lacks Bruce's physical/martial training and equipment. As a result I am standing by mah man Nigma. @the_poet: What do you think?
Sherlock and Batman meeting would be entirely non-canon.
Moriarty believes himself to be the greatest criminal mastermind to ever exist. But the Riddler challenges this idea that he could possibly be surpassed in intellect. The Riddler begins his battle of wits with Moriarty, and the battle can span across the entire globe.
