It's hard to determine the difference between Akatsuki Obito and War-arc Obito. Obviously, his prowess of using Kamui doesn't change, he's a master at it throughout the entire series. But the Rinnegan abilities he has is difficult to gauge. We know he can utilise it, as he has talked about using Human Path, and he can most likely use the Rinnegan to see through genjutsu and chakra networks etc (although that's useless because his Sharingan did that for him).

But I can comfortably argue that Obito's Rinnegan powers in general would be significantly weaker than Nagato's usage of it. Obito could only physically handle 1 Rinnegan compared to Nagato's use of 2. And bare in mind, Obito put the Rinnegan in his eyes for a very short period of time between fighting Konan and siding with Kabuto. Nagato had the Rinnegan his entire life, he is easily the most experienced Rinnegan user in the series. So assuming that Obito can use the Rinnegan powers to the same extent as Nagato is speculation at best.

I'm not arguing that Nagato definitively beats War-arc Obito, not in the slightest. But I think healthy Nagato stands a chance of winning, and Obito wouldn't even resort to his Rinnegan abilities just like he did against Naruto, Guy and Kakashi. And even if he did resort to the Rinnegan abilities, say for example a Shinra Tensei against Nagato's Shinra Tensei, Obito would only be able to partially nullify the damage, since Nagato's Shinra Tensei would most likely be more efficient with chakra and have more power, because Nagato's Rinnegan powers would overpower Obito's.

So in terms of strength/ who'd win in fights I'd put:

1. Eight Gates Guy (Although him fighting Obito is debatable).

2. Healthy Nagato War-Arc Obito (War Arc Obito wins 6/10 times)

3. Perfect Sage Kabuto (I'm not sure about a fight between Akatsuki Obito and Kabuto, would be interesting).

4. Akatsuki Obito

5. Pain (Technically Pain is stronger than Obito in terms of raw strength, but in a fight Obito would most likely win).

6. EMS Sasuke

7. Itachi

8. Orochimaru
