Admob earning vs pay2download earning vs inapp content
I know this is not really a one answer question. 

I have came across several people claiming that they would rather pay for an app 1-3$ and not have ads, and although many apps in the android market allow this option, not all of them. There are also many apps with in-app content (mostly in iOS), which I don't know a lot of people who buy...

So, Lets say I developed an android app with 1,000,000 downloads. In what situation will I earn more?

If I charge 2$ par download, I'll get 1,400,000$ (yes, my imaginary app is that good :) ).
If I use ad-mob (or similar service) will I earn more (for the sake of the argument my app is a utility app only used when needed) or less?
Is in-app content successful? I never got to use it...

*  I don't develop for mobile platforms, I might in the future, but this seems like an interesting question.
* If this question doesn't fit stack-overflow, Tell me and I'll remove it... I'm quite new.
