Which one usually earns more?

Hey,

I was wondering, with adsense on blogs which usually earns more? The way where the adsense is in the text like so:

http://blog.planet-gadgets.com/ (someone on DP)

or when its at the top:

http://www.electroniclovers.com (mine)

In the text and blended.

 

Okay, I have download adsense injection but what size would you suggest using on my blog? www.electroniclovers.com

300 x 250 or a similar ad block. The wider ad blocks tend to do better.
