I'm voting for Rumours as the sequencing is part of what makes the album a full listen, even for non-fans. I've heard it back in the day played in its entirety at parties and it works. I can't imagine it in any different order. Tusk is also great but I agree with a previous poster that we have to wait to long to hear Christine again after Think About Me. Tango is also sequenced well but Stevie is so out of her groove that it clunks at her 3 meagre tracks.
