I agree
Trick of the Tail is a great album, as is
Wind & Wuthering. I've yet to hear
...And Then There Were Three, but I have heard
Duke and
Abacab. Both have a few good songs ("Misunderstanding" is excellent, "No Reply at All" is pretty good), but overall I really don't enjoy those two albums. Beyond that I've only heard the singles from the rest of the 80s and early 90s.
My favorite
Genesis...the stretch on
The Lamb Lies Down on Broadway from "Hairless Heart" to "Anyway"...

Unbelievably great songs in there, they nearly all give me chills. Those are my most played tracks by these guys. Too bad that only makes 7 of the 22 tracks on that album. The rest are good but no match for those 7.
