That's pretty sweet maxi ... good job there mate !
I still see a lot of people saying Adsense is the best and I do agree, as its a lot more targeted to your page; pretty sure they parse your page and grab keywords and only show ads that match those. This will increase your clickthrough rate in return.

That being said, there are many spots where you can put ads so the best is still to try it out for a period and compare the results. Personally, I don't see any problem in having them both , and a couple others more for that matter, live as long as you don't overkill your site with ads.
