Firstly, as Seel stated...

"From the databook (translation not by me):

'''甦った現在の大蛇丸. '''The current reborn Orochimaru '''肉体のほとんどは柱間の細胞で構成されている. '''Most of his body is made up of cells from Hashirama. '''And since Hashirama's cells are the Kekkei Genkai that allows the user to create Wood Release, Orochimaru has it. • Seelentau 愛 議 20:07, November 22, 2014 (UTC)"'''

Doesn't matter if he didn't use during the war (I'm not going to look if he has since that's proof enough), he has it. And wood release is a deadly power whether you like it or not.

Secondly, Zetsu's body granted him access to Hashirama's easier natural regeneration capabilities (instead of the taxing substitution he utilized that greatly weakened him).

Finally, it's literally stated that the body greatly enhanced his power. Even going as far as stating it to be the reason he could control the Hokage at close to their maximum power.

"When Tobirama later declared that he was heading to the battlefield, Orochimaru's new vessel provided him with access to Hashirama's cells, allowing him to bind the Hokage."

Whether he has a new body or not, isn't relevant. At his prime he had Zetsu's body. He has every feat shown with the benefit of Hashirama's enhancements. Can't see how any other form is more powerful.
