Suggest between FB Complete and FB Fit 3!

A long time FB member here. I want to choose between FB Fit 3 and FB Complete.

Since I already have FB Strong, FB Sweat and FB Blend, I would like to choose a workout program that does not have workout programs that overlap with any of the above.

Also how overlap is there between FB Fit 3 and FB Complete? If there is very little overlap I might buy both :)

How does FB Complete (Advanced version ) and FB Fit 3 rank on difficulty level?

Advanced thanks for your responses as it will be extremely helpful for me to decide!
