To me the bottom line is about convenience and appearance. Any Ad Blocker you use must have access to your browsing history and active tabs else it could not perform it's function.
Ghostery, as it's name implies attempts to make you as "invisible" as possible which it does quite well and secondary to that function prevents targeted ads to a degree but at the end of the day, if you are on the web you are visible and your activity is being monitored if only by the sites you visit and the browser you use.
Preventing tracking as much as possible, ensuring your activities are not logged and encrypted in transit is the best that can be achieved. A good VPN and DuckDuckGo will do that for you, beyond that everything else is window dressing.
