Besides, just common sense should get it across if you'd all stop and think. Chōji can access a kinjutsu that generally requires drug-enhancement and takes Akamichi's lives. It's essentially his version of the eight gates, and he combines it with being the size of a boss summon. That ability easily makes him Kage level, and frankly, Sasori's relatively small-scale abilities would have issues with Gambabuta or Manda, let alone something their size using powerful kinjutsu. He's going to be obliterated very early on in that battle, particularly if restricted. A poison-less base Sasori triumphing is just laughable and proves how little this forum actually articulates their thoughts instead of conforming to old agreements of tiers, and even when unrestricted, most of Sasori's abiilities take time to prepare. Both summoning his puppets and letting the iron sand takes much more time than Chōji slapping his hand down on top of Hiruko, etc.
I'm extremely disappointed in this forum's response to this thread.
