They are Senju with a special life force, chakra quantity, power and abiity.. we know that. But I think Nagato is special among them all, which is why Madara chose him and which is why Nagato could wield both eyes with no drawbacks even as a kid. This may be speculation.. but I think Nagato may be Madara's child, I think he used Genjutsu to make Nagato's mother think that he was her husband on night.. then all Madara had to do was wait and put his eyes into Nagato.. Nagato even looks so much like Madara it's crazy, and he couldn't awaken his own Sharingan if Madara removed his original eyes before he had the chance to.. so that would be why Nagato was able to re-awaken the Rinnegan twice before it permanently remained active. His parents saw his eyes before that and obviously they were normal black eyes so they never had a reason to be weird about it, so I guess Madara chose Nagato for all these reasons. Third Six Paths is definitely a title he deserves.
