Its a hard question. The problem for me is that there are tracks of each album that I wouldn't live without. "No Jacket" has got a lot of standard pop-songs sounding too much like each other. But still "One More Night" and "Take Me Home" are supreme. I can say the same about "Dance In To The Light". Would still be sad if he hadn't wrote the title track and "Wear My Hat

". But in the end I decided to vote for the following 3 albums:
1. But Seriously - Has got most of my favourite songs. And then there are underated gems such as "Colours" and "Father to Son"
2. Face Value - I simply love "In The Air Tonight" and the rest of the record just keep up the level. But I don't like his version of "Behind The Lines

". An insult to the original
3. Both Sides - Most of the leading tracks of this album was some of the first Phil Collins I heard. And I like the dark tone of the album.
