I haven't heard the 60s albums but I do think Conversation Peace is pretty underrated. That said, it's way too long, and has some pretty clear flaws, so I'd say hex 8 or 9.

The Woman in Red is pretty flimsy as an album, and it will certainly be docked for frequently dipping into generic 80s R&B balladry, but it's still got some good Stevie tracks so that's at least worth a hex 5 or 6 right? I'd say it depends on your feelings for "I Just Called to Say I Love You" and "Don't Drive Drunk" - mine are mostly positive. "Love Light in Flight" is a clear highlight, at least.
