In addition to the stars being used for comparison among a single artist's work, it seems quite apparent that either a) most AMG reviewers suffer from some form of schizophrenia, or B) the write-ups and the "starring" are done by different people. I'm too darned lazy to research this, but I'm sure I've seen discs that were written off, then given mucho stars alongside ones that were praised highly but shorted in the star rating.
That said, I voted for Lee's Rumproller. As far as I'm concerned, of his "normal" discs (?!) this is the best. Overall, I prefer it to Cornbread and definitely to Sidewinder. On the other hand, I'll take The Procrastinator, Search for the New Land, and the live 3CD set over any of them...
