Prime Nagato is roughly the equal of the Gokage, adding Itachi tips it in Nagato's favor.
Indeed he is, but he doesn't defeat them alone if they have full intel on all his abilities.
- Ay's V2 Shunshin was one of the Gokage's best assets against Nagato. Here it gets neutralized by Itachi keeping Nagato within Susano'O.
Except Itachi protecting someone with Susanoo or even using Susanoo makes him

considering it appears beneath Itachi (through his Susanoo) and he is weighted down for good, and is done for.
- If Gaara tries to use Sand underneath their feet, then Nagato can absorb the chakra from it.
He can only absorb whats comes in contact with him, not what comes in contact with Itachi.
- None of Mei's attacks can bypass Susano'O or Fujutsu Kyuuin. Kōmu no Jutsu is blown away by Shinra Tensei or flown out of via Kuchiyose no Jutsu.
Mei's Lava will get rid of every animal summon besides that 3-headed dog that keeps multiplying, and that is vaporized to nothing so that it can't multiply anymore from Dust style. Mei's Hidden Mist takes away both their vision and they have to rely on Nagato's sensory which is worse than having their normal sight because they lose the Rinnegans shared field of vision and most of Itachi's eye related techniques besides Susanoo.
- Bansho Ten'in & Soul Extraction combo kills Tsunade without having to worry about her Regeneration.
But while hes pulling Tsunade to him Ay can V2 Blitz his head off. Mei would have mist up negating any shared field of vision he has to see Ay and Itachi protecting him with Susanoo means Onoki weights him down as I mentioned earlier. Gaara can sand shower him which would result in him using Almighty Push to defend and Ay swoops in on the cool down with V2 Chop and decapitates him.
- Jinton is hard countered by Fujutsu Kyuuin
- Multiple summons keep Nagato and Itachi from being taken by surprise with shared vision
While hes absorbing Dust Style he is vulnerable to Ay's physical attacks. Summons get melted by Mei and the dog erased by Onoki. Hidden Mist kills extra vision plus most Itachi's arsenal. Flight on Nagato bird won't help much, Onoki gives the Gokage flight or they fly on Gaara's sand. Planetary Devastation gets one shotted with a dust beam before it starts pulling mass. Mega Almighty Push (the village buster) can be tanked by Ay + Tsunade but Gaara's sand will protect them all from that anyway, and it would most likely kill Itachi.
So yeah, with no intel, Gokage lose no doubt but with full they win. They have too many nasty abilities and combos for the duo.
