I concur with previous statements, endless amounts of Sith have claimed they control the Force and use it as a weapon they wield.
All of them were full of it, Plagueis and Sidious have genuinely subverted the will of the Force, though it back-fired. Sidious despite lacking the midichlorian powers of Plagueis is stated to have tamed the Dark Side to a degree never before seen.
Most certainly the third is the most impressive.
