I can't compare the 2, because this is my 1st year homeschooling and I use CLE for my 1st grader.
I can tell you it takes me about 20 minutes to teach the lesson, do flashcards, speed drill and explain the independent work. There is virtually no preparation for me. I just grab the daily flashcards and go. Every couple of days, you have to move flashcards around, but it is no biggie.
If it is a topic that he has trouble grasping, it takes a little longer of course, but not much.
It is laid out very well and is easy to use. I love it, but again, have never used BJU.
