The corruption in itself does not reduce the power of someone. The things they did, being evil, was what made them less powerful. Morgoth was corrupting orcs, and in the Silmarillion it says that this took alot of his power. Sauron made the One Ring and put alot of his power into it. Morgoth lost the part of power forever, but it changed into his servants. Sauron held his power, until he lost the Ring in the battle with the Last Alliance.
So, both of them were evil as powerful as good... but when they did put forth their in people or things, they weakened.
