I use both - they take a different approach and are complementary

This choice is very dependent on your goals. Personally, I view Stock Advisor as a more conservative service that provides ideas that are balanced between value and growth. I believe Rule Breakers is a more aggressive service looking at companies that are smaller and/or "younger" in their Corporation age; I consider Rule Breakers a more growth orientated service as the name denotes.

Both services have a great track record. I'm a member of many of their services and I recommend to people to start with Stock Advisor - read all you can. It also depends on your investment experience. If after reading and following Stock Advisor then subscribe to other services. I enjoy their financial news and their podcasts also.

Neither, worst customer service I've seen. Scam borderline....

I've been with SA for 4 years with great results. I've never subscribed to Rule Breakers, but I'll give a hearty recommendation for Stock Advisors. As of Mid June 2020, the stocks that I've invested in through the Fool have returned 38% annualized better than the S&P500 in total.

i went for stock advisor, getting plenty of stock picks from there

If it is the only service you subscribe to I would opt for Stock Advisor as they have an excellent track record and more diversified offer.

yes to both
this line fills out the 50-char minimum

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.

absolutely not... pure waste of time and money.............
