buying affiliate traffic - better or worse than adwords?

I think there is much discussion about affiliate marketing with respect to its revenue. Does any know if the average quality of the affiliate traffic is better/worse than adwords on a cost/benefit ratio?

Any thoughts is greatly appreciated.

 

There is no way to make a generalized statement like this that would have any relevance.

Each source of traffic is only as good as the intentions of the people using the site.

How would you propose one measure the quality of traffic with out a specific source?

 

Why you have to buy where you can get thousands of interested people on twitter.

 

I think using adwords is much better
