In totality the band hit an artistic peak with Gabriel culminating in the LLDOB. Foxtrot, and Selling England by the Pound were also prog rock materpieces. I thought the first 2 post Gabriel era albums Trick of the Tale and Wind and Wuthering were excellent albums in their own right and compare very favorably with the Gabriel era material.
Things went downhill for me as a fan after guitarist Steve Hackket left the band. The followup album And then there were Three is not bad at all, very heavy in Tony Banks keyboards and overall melancholy feel. The single Follow You, Follow Me was preview of the popier sound the band would take in subsequent years. Duke is alright but Abacab to me was a fiasco and I lost interest them afterwards.
