NA's X I'd say was about on par with XIII, I stopped playing XII the very instant I finished, so I can't say how much fun the post game events were, but I've been told they're nearly as extensive and entertaining as X and XIII. BUT, when you count X International, that's when X destroys the competition. X also had very high replay value in comparison to some of the others. I've played through the whole thing at least a dozen times.
