The consensus seems to be 'Talk Is Cheap' and 'Wandering Spirit' are the best. I have to agree with that, though I think if you want the best look at what Mick would really sound like as a solo artist, 'Goddess In the Doorway' is it. It's truly representative of Mick minus Keith. That doesn't make it the best or even better, just an observation really. Wandering Spirit tries a little too hard for that Stones-y sound, IMO (probably the work of Rick Rubin as much as anything else). Talk is Cheap and Wandering Spirit, on the other hand, perfectly represent Keith minus Mick - good grooves, nice riffs, the occasional catchy chorus but many of the songs seem a little unfinished. That's because Mick wasn't there to help tighten things together. So I think 'Goddess in the Doorway' and 'Main Offender' probably best represent the deepest artistry of their respective artists, while I feel that, again - musically speaking, 'Wandering Spirit' and "Talk Is Cheap' boast the most satisfying and cohesive collection of songs. I have little to say about 'She's The Boss' or 'Primitive Cool', other than that they are merely average to my ears. And Ronnie's had some decent ones too, especially 'I've Got My Own Album To Do'.
