Avatar has a more complex plot than Naruto? LOL. Naruto's plot is 10x more twisted than Avatar is, which is one thing I really like about Avatar. Any major plot points are really long term ones (though this is less true in season 2, but still rings).
Dialogue is an easy one too. Avatar's in English, Naruto has to be translated. If Avatar dialogue isn't better, the writers suck.
Art? Avatar's art is unique, and Naruto isn't. I'll give you that one.
And don't flame me, I actually like Avatar more than Naruto, just like shutting people down when they make terrible statements. They're certainly different, but there are a bunch of similarities too.
