He isn't only proficient in doujutsu use as an Uchiha, but has the entire body half consisting from the Hashi's cells. Yeah, as an Uzumaki, Nagato is related to Senju, but he never was an Asura's reincarnation (whose chakra is a necessary component for Rinnegan awakening), unlike Hashi, and thus does not possess the as powerful "Sage body" as Hashi did. And since Obito has that kind of body, technically, he's comparable to a weaker version of Hagoromo - he has his both "body" and "eyes" power, although not the most powerful versions of them (which are wielded only by Indra's/Asura's reincarnations). In fact, this is the main reason Obito could control the Gedo Statue without the Rinnegan, as Madara noted. Thanks to these powers, Obito is much more suitable for wielding the Rinnegan than Nagato ever was.

Another question is the control of power Obito could get. As a person more fitting for the Rinnegan, he probably could access somewhat more power than Nagato did, but he tried to gain the control over it immediately and almost failed. Nagato got an advantage of having an adjustment period in his childhood and working on his Rinnegan power his entire life, while Obito needed to receive as much power as possible as soon as possible (due to the FSWW). Obito managed to handle the single Rinnegan immediately, with great issues of cource, but thanks to his he deduced that a second Rinnegan would be too risky in terms of possible loss of control over its entire power.
