I don't think Cloud is near equal to Seph at all. Sephiroth has toyed with him every single time they have fought. Plus, Sephiroth didn't use any of his abilities against him. I say Seph deals with Ansem, and Xemnas with ease, and Cloud is the toughest opponent, and yet, Sephiroth deals with Cloud quickly.
Regarding all of Xemnas' abilities I don't see how Sephiroth (KH or FF7) will prevail. Why someone decided to throw in Cloud (KH version or not) and Xehanort's Heartless I have no clue. Xemnas does not turn into a dragon nobody but he commands one (he sits on the throne), and having a harder time defeating Cloud does not prove Cloud > Xemnas at any rate. Gameplay-wise Squall is harder to beat than Hades.
Xemnas' respect thread. Somewhere on the first page I list his abilities and videos displaying them.

Squareenix has already stated that out of all of there games that they have made, including KH1, and KH2, Sephiroth is the best creation that they have ever created, and that there is enough to say that Sephiroth is superior to Cloud, Xemnas, and Ansem in every way. And if you have played KH2, and have read the guide, you would know this, and it states Sephiroth is the toughest opponent in the entire game. Seph wins.
