I have to say Hashirama is still stronger. Base Hashi defeats Nagato w/Gedo high diff. SM Hashirama takes this mid diff.
K11 survived Shinra Tensei with their fodder defenses. Hashirama has defenses strong enough to tank TBBs which are deadlier. He can survive ST. And Nagato will have to wait TOO long to recharge his powers after that, in which Hashi can comfortably destroy him. All ST gets defended against by Hashirama's wooden defenses.
Wooden Statue with Dragons can fight with Gedo Mezo. Poison gas suffocates Nagato. Wood jutsus are ridiculously fast, they can easily take advantage of Nagato's recharge time. Hashi can also fuse himself with his wood. Wooden hands from the ground are big and strong.
Chibaku Tensei is a bit of a bother for Base Hashi though. And that's the only reason I called it a high diff victory for Hashirama. SM Hashirama can destroy it or probably resist the force with Shinsuusenju.
Why does no one acknowledge that nagato never lost a FIGHT till naruto
That's probably because Nagato never fought anyone as strong as Hashirama. And SM Naruto is a joke compared to Base Hashirama.
