Explain especially if you choose the "other" option. 

But the era I really love is Peter´s era. Like quite much also that first pop album.

I'm not a Genesis fan. I have a conflicting relationship with Genesis.

I have great respect for their work, and I consider them damn serious, competent and... middle-class prog. I consider Gabriel the genius of the group, and the acoustic parts with Gabriel-Hackett the most engaging emotional. 

I consider Banks a very good instrumentalist but with a musical sensibility as a bureaucrat, and I don't remember any of his solos that made me enjoy like a hedgehog. In general, it is not a band that is characterized by solos and actually who seems to me most technically gifted and capable of spectacular games on his instrument is Phil Collins.

I consider their discography from Trespass to A Trick of a Tail very good, but his level is not one of the higher. The records I consider best are Trespass, the only one without weaknesses, and The Lamb, that is, those that deviate from their standard prog. Trespass is a little jewel, the only one I can say I got great pleasure to listen to it from the beginning to the end... Because with Trespass the pleasure touch the heart: it's the most melodic album: I feell emotions with it, instead the other albums produce more pleasure to the brain. 

Nursery Crime in my opinion is a minor work, instead Foxtrot and Selling England by the pound are ambitious operas but they dont reach the peaks of other groups because they have some weak songs.

In particular, A-side of Foxtrot is not so great and B-side of Selling England is weak.

Their best sequence are the firsts three songs of Selling (Trespass sequence is close), in particular, the first and the third: they are exceptional, a touch of genius and so, when I listened to them for the first time I was excited, but with the fourth song my humour went down... and the level quality of the second side is really modest.

Foxtrot and Close to the End, in my opinion, are ambitious works, without big falls and very well-groomed, they respect all the patterns of prog (such for which they are, how to say?, The common ground within which the various genres of the prog move) but they lack the ingenious flick, they are very elaborate and sometimes sophistication hides a scarcity of immediate melodic inspiration.

After A Trick of the Tail I consider their albums very modest.

Ok, my opinions.

My favorite era, though, is:
Trick of the Tail

Wind & Wuthering

Spot The Pigeon

And Then There Were Three

I always say I like these because this is before Conny Plank told Phil he was a soul singer.  After this era, I gravitate to the Banks songs preferably.

Also, I'm a big fan of:

Rutherford's Smallcreeps Day

Banks' A Curious Feeling

Something about that mid-late 70's era I like.  Might be the David Hentschel production.
