Without spoiling too much, both of these do have similar settings and moods. They both have very well animated fights, fantasy/sci-fi settings, and both begin with a fairly large plot twist (though if you didn't see Sword Art Online's coming from a mile away I don't know what you were watching). They both have their flaws, one more than the other, but are enjoyable fantasy series nonetheless. Deca Dence has a bit more of a message to say, but if you are looking for something fun and enjoyed one, you might like the other.
