I've been using Privacy Badger for 6 months and I can't recommend it enough for non-technical people (or technical people that don't want to debug websites all day long).
The one problem I've found is that certain services that use a bookmark/iframe combo (instapaper, for instance), create problems because you want to whitelist instapaper, but aren't given a chance. For that, I recently found: https://tsibley.net/provoke-the-privacy-badger/
But it's based on AdBlock code. I started using uBlock instead of AdBlock Plus in order to save some resources. It seems that adding Privacy Badger would introduce that performance hit to the equation again.
