'Sigh" What don't you get. The Androids were created by a genius known as Dr. Gero, they were perfectly designed to take down Goku, and that's why a SSJ was nothing to them and know one touch them at that time. The Androids had files on all the Z-Fighters. The technology that King Cold used to repair Frieza was far less advanced to Dr. Gero's technology. It's all because of the mastermind Dr. Gero, that's why the Androids are stronger. Plain and simple.
