I'd say that Aslan is definately more like a Jesus figure. In 'The Lion, the Witch and the Wardrobe' Aslan sacrifices himself according to the Emperor's magic and laws. He makes it quite clear that it is impssible to go against the Laws, which suggests that Eru is much more on a par with the elusive Emperor who never shows himself in Narnia, but is represented there by Aslan in much the same way as the Valar represent Eru.
