I actually did run comparison test for our client - regular product retargeting (a site that is very heavy on educational material) vs content retargeting (specific landing pages with content). The engagement level on content were off the charts (up to 90% download rate, TOS, Bounce Rate). So educating works far better. Only trouble is, you need email, which 95% of visitors are not ready to give you on first hit - that's why retargeting works so well here.
