I was homeschooled and I remember using one of the Editor in Chief books (I don't think CDs were an option then). I remember that I really enjoyed it, but it was just a supplement to other things we used and I don't remember what they were.
My kids like Editor-in-Chief stuff, but I wouldn't call it a curriculum. More a diversion, a supplement. We're pretty much unschoolers, so for my kids the main curriculum was life, and interests, and such. No experience with the other one you mentioned.
