I'm pretty sure they are all S-Class Mages too, but I do think that Rufus is stronger than them. I mean, we don't know the details about Memory-Make, but it seems that he can memorize any kind of magic. Think about it. He'd be able to use even Gildarts' or Bluenote's magic, maybe even Mavis' Fairy Glitter or Makarov's Fairy Law.
