IMHO, both are very good rigs. We choose the CC over the Big Country (and others) for the following reasons:
Curved roof
Return Air duct in both BR and LR for A/C making them somewhat quieter.
Exteriors walls are not laminated
No window in the entry door.
Lazy Boy furniture
Space around the king-size bed in the slide. More elbow room at the head of the bed.
A built-in clothes hamper in BR
Built-in trash can(s) in bottom drawer in kitchen
Lots of pantry space.
and most of all DW loved it :B
Good Luck
