Deidara scales above sasori
Deidara >>> Sakura >> Sasori
> Deidara admitted inferiority to Sasori
> Deidara, despite his arrogant attitude, refers to Sasori as master. This is the same guy that blew himself up due to his excessive pride and ego
> Sasori defeated a stronger Kazekage than Deidara
> Sasori has more hype, defeating an entire nation, defeating the strongest Kazekage, etc
> Deidara doesn't dare do anything when Sasori disrespects him
> Just look at how Deidara treats Sasori and how he treats Tobi. He's basically worshiping Sasori because Sasori is stronger, whilst Deidara thinks Tobi is weaker and thus bullies him and disrespects him
Now to the actual battle
> Sasori counters C4 because he does not need to breathe
> Iron Sand is superior to Gaara's sand which was blocking C3 and could thus block all of Deidara's explosives besides C0
> Sasori can fly using his puppets and his puppets can fly as well, so Deidara no longer has the aerial advantage he most often does
> Sasori can snipe Deidara using Iron Sand and he just needs one scratch to win
> Iron Sand Needle Sphere will land at least one hit on Deidara
So yeah Sasori has the offensive means to put Deidara down while having the defensive means to protect from his attacks.
Only chance Deidara has is C0, but that's basically just a tie.
