Yet you fail to know that Nagato is a master sensor, so sneak attacks from Obito are out of question. About Obito's Kamui "The right eye's primary weakness is that the user must solidify in order to utilise Kamui's teleportation, resulting in a brief period in which they are vulnerable. This deficiency means that the user must also materialise when ejecting stored items, presenting the same vulnerability. Additionally, the sections of the user's body residing in Kamui's dimension can still interact normally with anything inside said dimension, meaning the user can be damaged by such items. Obito could only maintain his intangibility for approximately five minutes at a time, and it took him longer to absorb himself than another person or object." Directly from this wikia with sources. Nagato has this in the bag, Obito is a corpse.
