The short version is that Sephiroth's is better when you can use him, but you're going to be using Cloud way more often, especially since they already said Seph is getting particularly few banners. Cloud is therefore better value. The only thing going against that idea is that the model for Cloud's next UW has already been datamined so he is likely going to be one of the first to get a 3rd UW so some people are picking Sephiroth just in case Cloud's new UW just obsoletes Ragnarok.
