Tor is a another huge step for remaining anonymous but people have been caught while using Tor. Its pretty damn hard to be a complete ghost because there's a million ways to screw up and it only takes one to catch you.

A VPN plus Tor does a really good job, but neither of those protect you from the human element in getting caught. If you're just going to post an edgy meme or buy a few hits of acid, you're probably fine. If you're going to do something like running an illegal marketplace, doing only those two things is liable to get you caught at some point.

I agree.... that's why I said: ***"if used properly"***

If you just download an Tor Browser on a Windows machine.  
You are not anonymous!

But if you use it via TAILS or Whonix you are good.

**edit:**  
Maybe I'm not completely objective on this matter.  
I've a Computer Science degree and an interest in Cryptography and Anonymity.  
And even for someone like me it took years to learn how to use all of this properly.
