Consumer Reports just published (as in last week) a report[1] surveying a number of these services and found almost all of them to be a little bit effective, none of them to be highly effective, and the cheapest of the lot to be the most effective (EasyOptOuts).

Of note, opting out of a service by yourself by hand was only 70% effective ($0). Using EasyOptOuts was around 65% effective ($20) and using Confidently was only 6% effective ($120).
