I use Privacy Badger with Ghostery and have been really happy so far.

I rarely run into situations where I need to fiddle with both to unblock a script or embedded video, but for the most part the combination is pretty reliable.

I also like seeing the long lists of adware Ghostery is blocking as the page is loading. You'd never know some pages have 50-60 scripts getting loaded to track what you do. It was an eye opener the first month I was using it.

I got a new computer and was browsing around, and it seemed that the entire web suddenly got much slower and ad-ridden. It was horrible, until I remembered I forgot to install Ghostery.

Why do you use both, though? Aren't they pretty much perfectly overlapping?

They do, albeit in different ways. I use them both since there's stuff that Ghostery misses that Privacy Badger picks up and vice versa.

Plus with Privacy Badger, it gets better the longer you use it:

The salient difference between Privacy Badger and the other extensions is that Privacy Badger’s blacklist is generated through heuristic blocking, which means it gets better the longer it is used. Out of the box, Privacy Badger won’t block nearly as many third-party requests as the commercial options, but as you use it more, it will learn more and more hosts to block
