I think that Zabuza could defeat Orochimaru when his arms were sealed.
Orochimaru when having his arms disabled was only able to fight with his Kusanagi sword from his mouth. However, his Taijutsu with that doesn't compare to Zabuza's. Orochimaru had a 3.5/5 for Taijutsu in DB, Zabuza had a 4.5/5. Plus he has more physical strength.
Also, Orochimaru has no counter for the Hidden Mist Jutsu and he won't stop Zabuza from putting it up because Guy is faster than him and Zabuza put it up in front up him, Kakashi, Rock Lee, etc. when he was an Edo. That being said, he will definitely be able to put it up against Oro.
Since Oro has no counter for Zabuza's mist and doesn't have the Sharingan to read Zabuza's movements, he will not be able to keep up with him and will fall to him. Most likely get caught in a Water Prison.
Oro without his arms also won't be able to dodge Zabuza's Water Dragon and Giant Vortex Jutsu, they are just too big.
BTW Kabuto summoned Manda using Orochimaru's summoning tattoo on his arm, so Oro will not be able to summon Manda on his own.
Thoughts?
