No, it's because he's a full-blood demon and Inuyasha is a half-demon. It's like the difference between Inuyasha's full demon form and his normal half-demon state. The Yokai that a full demon has is stronger than a half-demons, but because Inuyasha's father was such a massively strong demon, even Inuyasha's weaker half-demon power is still more than most demons, and when he becomes a full demon, even more so. The reason Sesshomaru is still stronger is because he and Inuyasha have the same father. Basically, Sesshomaru is an example of what Inuyasha would have been if he was born a full demon instead of a half-demon. But as they pointed out, if Inuyasha wasn't a half-demon he wouldn't have had the same heart and emotions that he normally has. Its these qualifications that give him the right to use Tessaiga, rather than Sesshomaru who simply wanted it for power. In fact, that was the whole reason for the sword selection, Tessaiga was designed to only be used by those who cared no hatred towards humans in their heart, and Tenseiga was designed to teach the user the value and importance of life. It was clever way for their father to teach the brothers what was important in life.
