I'm a Jman fanboy, but I'm finally admiting Oro as superior.
A. We have never seen Oro's true strength despite being major antagonist.
B. It's safe to say since his fight with Hiruzen he has gained more jutsu and intel.
C. He took on four-tail form Naruto in weaknd state and was having fun.
D. He's still alive!
Sorry Jman your still my favorite pervy hermit sage.
