I like Still but not Bankstatement. A Curious Feeling and Strictly, Inc. are probably his two best solo albums, though, IMHO. I used to be a big fan of Tony's as he was the person most responsible for som great Genesis songs from Firth of Fifth and most of the music on Wind and Wuthering through to some of the more interesting 1980s material like Me and Sarah Jane, Evidence of Autumn, Domino and The Brazilian. I have gone off him a lot though due to the cheesiness of some of his synth sounds and the morbidity of a lot of his lyrics (says I, a DeathLister!) especiallywhat he was composing on And Then There Were Three but even some of his more modern doom-'n'-gloom-fests too.
I think that Tony's biggest problem is that a lot of what you refer to as doom n gloom fests effectively come across as a little whingy. He was born into privilege and has been successful from quite an early age. So what comes across is middle class angst rather than an expression of the futility of existence. I still think he is a very clever writer and some of the early Genesis mythological tracks owe him an awful lot.
