I agree that the self-titled is the band's best work, but Cove rejoining the band wouldn't solve any of the problems that led to his departure. His live performance stinks, and I'm assuming it hasn't improved in the past few years.
The last time I saw the band was about a month or so before he was kicked out. The band looked defeated and the crowd was dead. Anthony rejoining for this short stint really is the best thing for Saosin, both financially and from a relevancy standpoint.
