Favorite Genesis Album?

This past week I've been on a Genesis kick. I've been shuffling around albums like Foxtrot, The Lamb Lies Down on Broadway, Selling England by the Pound and Nursey Cryme with reckless abandon. All of which are obviously stellar. Prior to this week I've always felt fairly certain that Foxtrot was my favorite Genesis album, however, after listening to Selling England by the Pound over and over again these past few days, I'm starting to question my opinion. Selling England by the Pound seems to be growing on me more each day, which has me wondering, why didn't I view it this way before? Has it become my clear favorite? Not quite yet, but right now it's tied with Foxtrot, and its stock is rising. Anyhow, I'm going to keep this short and sweet. I'm curious to see what's your favorite Genesis album.
