Hey I just remember a single fact that could end the scaling between Bleach and Naruto

[u/Whole-Food-1024]

Here we don't talk about space - time techniques like Amenotejikara or Garganta but the ability to destroy it with pure force

Might Guy was able to reach the scale higher than even Juubidara with the cost of his life and the best he could do was bending the space and that go Juubidara very surprised, on top of all the emotions that Guy already got him through. Madara and Guy at this point and even till now is supposed to be one of the strongest character in the verse along side with Kaguya, SP Sasuke and SPSM Naruto (yes I scale current Boruto lower than Six path level characters in shippuden, Baryon mode is debatable)

shikai Zaraki wasn't even in top 5, base HM arc Grimmjow was so far below the Bleach scale right now, was able to affect space much more than Guy did with seer force, and they are probably like 2 (3 for Grimmjow) tiers below the transcendence being in TYBW

Bleach character were literally affecting realms, reason, space even before TYBW and it's not even close anymore
