They're all great.   I lean heavily toward close-harmony duets--have been called a harmony slut-- and Kate and Jody are just wonderful in duet. My favorites are probably:

A Song That Will Linger--especially a haunting "Shut Up In the Mines At Cold Creek", wistful "Red Rocking Chair", good solid Carter-family style " Orphan Child"--and an absolutely stunning "Lovers Return".

Our Town--just wonderful "Going To the West", exquisite close-harmony "Home" and "Too Late, Too Late", gently rocking and hypnotic "Our Town", and a solid traditional version of the old Christian Harmony "Twilight is Stealing".

Stay Awhile--sly "Seventeen Cents", great "Blue Mountain", and wonderfully spare "We Shall Meet Someday"
