When I gave up on Adsense Deluxe for WordPress and used Adsense Manger it was a easy choice. The Adsense Deluxe was not updated for over a year and new versions of WordPress kept on coming. But there is a bug in Adsense Manger.
Every time you update Adsense Manger it goes back to the setting of donating 3 % to the creator of Adsense Manger. Well I have nothing against him personally but I want to set if I want to donate anything myself or not. I do not want it to be a default setting that I can miss very easy.
So when you upgrade or install Adsense Manger for WordPress just make sure you set the percentage as you want it, dam you can give him 100 % if you like
