Best Article Automation Service?

I was wondering what you guys think the best article marketing automation service is. I have been using Article Marketing Automation for a month and I am not sure whether I see any results. Here are other programs that I found:

Unique Article Wizard
1waylinks.net
SEOLinkvine
Free Traffic System
ArticleRanks
Article Marketing Automation

Please let me know which article automation service you find provides the best results and why? It doesn't have to be on this list.

Thank you

Try all services for better results

If I had money/time to try them all, I would haha Did you try any of them?
