He wasn't mentioned in the story as much as his younger brother, but he did do many great things in his campaign for Jiang Dong. He took out Yan Baihu and Liu Yong. He did those in a matter of a few years, normally it would take a Shu general a while to counquer such territory.
Sun Jian wasn't mentioned as much as Sun Ce though. I think that Sun Jian should recieve a little more credit, though he is very greedy. But I heard in the real history, that he DIDN'T steal the Imperial Seal, it was just a brush of bad luck that he was killed.
So I think Sun Ce would get more credit if he would have lived longer, and perhaps been a little bit nicer.
A beautiful face can win popularity, but a beautiful hand can win respect.
