Well i say he spent more time with Orochimaru because of the 3 year gap. When he was in the village he really didn't chill with Hatake. You could say Hatake cause of the missions but it really boiled down to actual presents. I think Oro takes that because orochimaru trained him for those 3 years while when he was with Katake all he did was learn the thousand birds tech (Chidori)
& again he ressurected Orochimaru & praised his power by say don't underestimate him while dissing Hatake in the war an that half ass apology.
Yea Sorry!
