Obito at 14 was an inch away from winning (which he mentioned was possible, and Minato confirmed). Now, Obito is keeping up with BM Naruto (whom fanboys love to tell me is able to blitz any opponent at any time.) Without KCM, Minato is losing to Obito.
MS Obito is unbeatable 1v1.
It is not like he pushed Minato to his limits nor it is a high dif match for Minato,Minato don't have any chance of winning against Obito coz he can't land a blow, that dosen't mean that Obito can obviously win that fight as it is a gamble for both of them.
FTG is still faster than Kamui so Minato can counter Kumui & Minato's reactions are still > Obito as well as BM Naruto,So it is only logical to say that Minato > Obito.
Minato chances of winning against Obito are > Obito's chances of winning against Mianto.
He can use that poison sand to change the area into a poison play ground, while having his one hundred puppets in the air causing a ruckus aswell. Kazuzu provides supports for the puppets with his hearts and their elemental techniques, if Orochimaru is here, and he can get a hit on Minato, FPS gg. Kisame spams sharks and suitons, Pein Shinra Tensei's Hiruzens fodder shuriken.
Ur ignoring Hashirama while saying all this stuff,It takes more than one Akatsuki member to hold Hashirama.
Sasori can do that but his sand is not as fast as FTG so they can avoid it pretty easily.
BM Minato can takeout all of Sasori's puppets with a single TBB.
