Good battle OP. Personally from feats, Nagato still has the greater gravitaional feats. He was able to crush the entire city of Konoha whilst using a remote body (Yahiko) and then created a chibaku tensei so strong that is took the most powerful attacks from Naruto, Bee and Itachi to destroy it. We have yet to see Fujitora use his abilities to create anything so powerful as of yet, yes he can summon meteors but the ones he summoned are no where near as large as the one's Madara summoned with his rinnegan.
Also remembering Nagato quite easily defeated both Bee and Naruto in his 9 tails chakra form, he's definitely a powerful opponent.
It's very 50/50 for me, Nagato has better feats but Fujitora has more hype because he is admiral level and should be standing at the very top of the OP world. Slightly leaning towards Fujitora because of the hype though.
