Have to agree.
Adding Obito: Just a rag-doll. As the masked man, he was just adopting Madara's persona, and doing Madara's work. Then when it came off, it was revealed he was this weak-willed guy who barely managed to stumble his way through the story until death. His primary arsenal as an adult consisted of Kamui and one Katon, with the occasional bukijutsu and basic Mokuton technique for good measure. As Juubi Jin, he was interesting and convincing as a threat for 1-2 chapters, but just fell off.
Then when Madara was revived and started solo'ing like mad, Obito looked totally pathetic as a threat, especially considering his power against eyeless Madara.
