Rufus was a good character and definitely one of my favourites from FFVII, so I agree with the last post on that front. I disagree about Cait Sith though. I really liked the role he played in the story because it showed, first of all, that the Shinra weren't a single-entity of evil like Hojo, Scarlet and Heideggar but that there were good guys within the monolith too.

I'll agree on Red XIII and Barret. I think the disc one scenes at the Cave of Gi and the desert are both very touching in their own ways.

Cid was the first character that sprung to my mind, however. I liked his development and his backstory about how he had this dream he'd always wanted to fulfil, but he stopped it at the very last moment to save his friend who would be willingly sacrificed otherwise.
