Here's the stats:
LinkBucks: 89 clicks and a total of $0.0411 = 0.0005 per click, which equates to $0.30 after 611 clicks.
Adf.ly: 611 clicks and a total of $0.96901 = $0.0016 per click, which equates to $0.97 after 611 clicks.
What I liked
I did like LinkBuck's services and tools however, for example their full-page script was easy to configure with domain exceptions via a handy text box and drop down submission system, while with Adf.ly you have to configure it by entering an array of domains in the code.
Adf.ly is going to make me more than two thirds more money than LinkBucks, while LinkBucks can be easier to use and I like its features. In the end, money matters, and while Adf.ly doesn't have the features, its payouts per link are much higher.
