Ghostery blocks ad-trackers and other add-ons that slow down your experience online as well as prevents targeted ads when you visit other sites(a marketing team's worst enemy). Sometimes because of the blocking I get ads on Youtube that are not in my language, but that's not a big deal.
Pros
Blocks ads online including annoying pop up ads on certain sites
Prevents people being able to track you online
Oh and it's free
Cons
The only one that I can think of is that sometimes I get ads in other languages. Not a big deal

Pros
Ghostery makes the internet less intrusive by preventing some of the tracking that is going on today.
Cons
Ghostery is not available for Safari on macOS yet, that is a bit sad for me, else they do nothing wrong.

A great browser upgrade for the privacy-conscious people out there.
Pros
No one like being tracked online and Ghostery is probably one of the best ways to mitigate the tracking of your online persona. The service is an extremely easy to use as a browser extensions and it helps with securing your data, especially by preventing a lot of ads-related scripts from running and gathering your data.
Cons
It's not as powerful as some other ad-blocking extensions so you will see some ads on most sites even with the service running.

Pros
What I like about Ghostery is how they explained how it works. I think it's easy to use and you can find it on any browser as an add-on. It's always recommended!
Cons
It takes time to get the full benefits, which is not their fault. and it doesn't replace the ad blocking app. So, you'll have to use another app to block ads.
