If we consider them both being at their best, and that means Sasuke from his last fight against Naruto, then Uchiha would mop the floor with Toneri. The strongest Sasuke fought on par with the strongest Naruto, while all it took to defeat Toneri was one punch from Naruto in Kurama mode. So yeah, Otsutsuki has no chance in this fight.
