1) Yes, they were. Kabuto was inferior to Orochimaru and Oro created only almost perfect Edos when he brought back the Kage. The almost implying they were still nerfed, thus Kabuto's Edos were even more nerfed.
Sage Kabuto was stronger than Orochimaru, it is also stated that his edo's were near perfect copies of the originals, with Madara being beyond his prime
2) Again, Konan was much weaker than Nagato. We are talking about a full powered Nagato here with all his Paths and full energy reserves.
Again Konan literally baited Obito into a trap after 17 years of planning, with enough prep time and resources she's killing almost anyone in the verse. Full powered 6 paths Nagato is not surviving that trap.
3) False. He already had the Rinnegan since that happened after he killed Konan. Also Minato never even saw full powered Nagato to compare them.
nope, Obito met with Kabuto in chapter 489, he fought Konan in the early 500s.
Do you srsly believe a guy who killed Hanzo, killed Jiraiya, killed Mangekyo Kakashi, and destroyed most of Konoha on his own
You understand Obito can beat Hanzo, Jiraiya, MS Kakashi and destroy Konoha? In fact if it wasn't for Minato he was going to destroy the entire village with a fully controlled 9 tails.
Let me remind you that chibaku tensei couldn't control an 8 tails kurama with half his chakra missing. Obito can control a full chakra 9 tails on a whim.
and needed to be dead before Obito dared to make a move and grab his Rinnegan is weaker than Obito? Are you for real now?
Obito always planned on using Nagato until the last second as shown below:
Also I'm dropping this now since it's bordering off topic territory.
ok, but if you're still not convinced check these vids out;
Naruto powerscalers almost all agree that Orange mask Obito was the strongest Akatsuki member, these are two of the largest powerscalers
