[Doctor Who] What does the Doctor think of his past regenerations?

We already know how much Ten loves Five. What does Eleven think of Four or so on?

Generally speaking, later incarnations tend to look down on/be annoyed by past incarnations, and past incarnations seem to be skeptical about later ones. The First Doctor treated Two and Three like children in *The Three Doctors*, which is odd as they're technically older and more experienced than him; what's odder is that they reacted like they were younger. Six and Two argued quite a bit, and Six treated Two like a disobedient child. Ten and Eleven got along better than any other pairing we've seen, except for their brief argument over Trenzalore; they behaved like similarly-aged siblings, despite having several hundred years (possibly) between them.
