Luke defeated DE Sidious (with Leia's help, but that only negated the Force advantage) and Yoda realistically defeated him in a lightsaber duel also, who was also said to possess unequaled skill.
On the other hand with Vaapad to negate the Force advantage, Sidious perfectly stalemated against Windu, whom Yoda is also superior too.
