Well. In my opinion "Google Adsense" is the best advertisement provider. You know it is not easy to get a Google adsense account. They give more money for traffic than any other Advertisement network in the world. Also Google Adsense are trusted by thousands of people and Google Adsense is the only reasons that everyone is try out for Blogging!.
Other Advertisement provider like Chitika also a good company with promising payout still not better than the mighty Google adsense. And also Google Adsense is easy to cash out while other may find some difficulties.
So these are may be the reason why Google Adsense is the number one Advertisement provider in internet world. it's my opinion. I don't think there are many people who are against Gogle Adsense's performance.
Thanks & Regards,

My personal experience is that, if you compare Adsense with some other ad networks, the revenue generated with Adsense is much more than others. However, getting an Adsense account these days has become really difficult and you need to have a very good blog with good content and reasonable traffic from search engines.
Other ad networks mentioned by you, like Chitika and Infolinks are also good. Infolinks is mainly in text advertising networks and Chitika generates good revenues for traffic from western countries.
You can try all advertising networks yourself and see which suits best for your blog and traffic coming to it. The one which performs well can be used by you.
