When Gaara was still the Shukaku Jinchuriki AND the Kazekage Chiyo said quite blatantly the Third Kazekage was the strongest Kazekage ever.. Even with Shukaku's power she made it clear Gaara was weaker than him. Nagato, Itachi, Hiruzen, Tobirama, Minato, the Sannin, Sage Kabuto are definitely above Third Kazekage so are 6-7th Gate Gai, Kisame, Sasori(obviously since he killed him), Obito, Shisui, Izuna.
