PC based Instrument rating course opinions?

Folks,

As I train for my instrument rating, I'm in need of a CD based ground
school. I'm familiar with the King courses, as I used the King PP-ASEL
kit to help with my Private. I also took an instructor led PP ground
school, which only taught me how much I learned from the CD's.

Before I pull the trigger on the King courseware, can anyone make a
compelling case for a different program?

My instructor is fine with whatever course I choose, we do one on one
ground instruction as necessary.

Thanks!
