They’re both pretty equal. But they both have different techniques. I chose deidara cos he is the only guy in the starting of Shippūden to make a Nuke. But Sasori counters with his 100 puppet technique. To be fair, their pretty equal. Plus the third kazekage puppet.
Skills, iq, biq, techniques, stealth, Sasori wins.
Brute force, definitely Deidara.
Short term battle, Deidara (if he brings enough clay)
Long term battle (3 hours onwards), Sasori. If both go all out, probably sasori. Deidara does take heck of a long time to make his “art”. But it is hard to say.
