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 in terms of strength I'd put:

1. Eight Gates Guy (Although him fighting Obito is debatable). 2. Nagato ~ War-Arc Obito 3. Akatsuki Obito 4. Perfect Sage Kabuto 5. Pain 6. EMS Sasuke 7. Itachi 8. Orochimaru
