All of them. There is no wrong album. They were on top of their game in the progressive years and they outright dominated the 80's pop years, be it the band or the solo efforts of the artists.

Heck, even their oldies-sounding debut from the late 60's was a cut above a lot of the other groups that got all the airplay on the radio. You really can't go wrong no matter what you choose.

But given the personal preference. My Top 3 favorites in order are...Trick of the Tail...Duke...Foxtrot.
