Alex Boss reviewedCaptain Growth for Facebook AdsAI that finds bottlenecks and growth points in FB marketing
 RecommendedPros: 

Allows to see insights that are usually overlooked by traffic managers

Cons: 

High barrier of entry price-wise, however it's ok for large clients

Would be interesting to see Wickedreports or Kissmetrics integration in the future, so analysis includes LTV and real sales data from CRM and other stuff that GA and FB skip.
