Both Dominion and DC are deckbuilders, but they play completely different, and aim for different target people.If your gaming group wants to prove who is better at Deckbuilding, then organise a competition with Dominion. Dominion is eminently a strategic game: you see the initial 10-card-pool, and you build up the strategy to follow. Basically it's this, though sometimes you have to be open-minded because, against the odds, you do not pull the cards you need (buy Chapel, and in the first two turns with it Estates don't appear with it), so you have to slightly adapt to what you have and what you can get. But after many many plays, usually the best strategic player may get a higher win ratio.
Besides, playing 2 or 4 don't change the game too much, since (unless lots of 'attack' cards are present) there's not much interaction.
DC is a DBG with a different approach. This game is more LUCK-sensitive, only 5 cards are available at a time, and they keep changing along the game. If you control a 'situational' super-hero (those relying on a determined type of cards such as Batman, Superman, Wonder Woman or Flash) it can happen that you can't buy the cards you want and cannot trigger your ability. Or just the opposite, that you can do that every turn and rule the game. Super-heroes also have good and bad days ;). GreenLantern, Cyborg or Aquaman are more robust or less luck-dependant.
A 2 player game allows each player to have more control, and can be more psychological and strategical. The more players in the game, more interaction, more chaos, more tactical and less strategical.
All in all, I can't imagine a tournament with DC. Which can be good or bad depending on the user. Since I don't like competitions (but I always play to win) and I like just to play and have fun, for me and our group this game suits us better than Dominion.
And yes, don't think of Batman with heat-vision or Superman on a Batmobile, but superheroes helping each other. Because in the comic books, you can see they often help each other, but sometimes they may disagree and eventually fight each other. That's the game as well.
