I subscribe to both. I started only with Stock Advisor, then did so well I decided to subscribe to all of the products for one year to see the differences. After that year, I reverted back to only Stock Advisor. Recently, I have re-added Rule Breaker, as noted above by another, they have different approaches and I have an interest in at least following both... still maintaining the final decision as what to invest in. In part, I don't want to spend the time to analyze too many options and am satisfied with what I can gain from these two.
