I'd say the dead Gungans were a pretty unemotional moment compared to the dead Ewoks. Not to say the Ewoks inspired a great amount of attachment, but you felt sorry for them in the sense that they were caught up in a war that was bigger than they were I guess. Little, noble, trustworthy creatures versus the treacherous empire. Made things interesting despite the unrealistic successes they had.
I liked the Gungan battle too, but mostly for the flow of the combat and not much else.
