Is there a better curriculum?

Mike’s Blog and his readers banter fairly about LifeWay materials in the context of “Deep” Bible Study and Sunday School. On the other hand, Jeff Lee comments at the Boar’s Head about switching his class away from the LifeWay Family Bible Study to their Explore the Bible series, and he adds, “I’m still looking for a better curriculum for our class.” Are you satisfied, or dissatisfied with LifeWay’s Explore the Bible series of lessons? What alternatives have you considered?
