Auto Click vs Unique Visitor

Well let me start off by telling a little bit about myself. I’m a native born United States citizen, of legal age, and I have some decent talent at application development and programming (learning html and css very fast). Now with me being a relatively new member around here, what exactly are the difference between "fake visitors" (Paid to click/Bot) vs Real Visitors?
Of course the real visitors gives you much more potential to generate income and having a steadier daily traffic; but other than this, what is the main difference?
How much are you willing to pay for botted, "fake visitors" vs unique visitors? Here would be an example I am looking for:
I would pay:
$100 for 100,000 fake clicks and I would pay
$1,000 for 100,000 unique (not botted/PTC) visitors
Thanks for your help/
