But I've heard you can get more power out of it! and I like that!

You get more power out of ethanol because it has a very high octane rating, so you can go crazy with compression and timing when using it.
You are right about energy content. Ethanol has about 2/3 as much energy per gallon than gasoline. An engine that gets 20 mpg on gas would get about 14 mpg on E85 if all other factors were the same.
