Ironically enough, I'm not going to say Edge, as I can see why people would think kinda dismiss him (I thought his cocksure attitude was a refreshing break from Cecil's uncomfortable love triangle, and brought back the lightheartedness that left after SPOILER IS OLDYang's and Cid's apparent deaths).

I think that at least Story-wise, Edward is sorely underrated. I remember being shocked that Cecil hit Edward while he was mourning his dead girlfriend. I would have at least given the man a solid 5 minutes before decking him one. Also Edward completely redeems himself in the end, not sure why everyone maintains such a strong opinion about him.
