Certain sites like EzineArticles and PRweb tend to rank better organically which can help increase traffic, while other article sites are better for gaining high PR links.

A Few Quick Optimization Tips
You want to be careful with submitting the same article to multiple submission sites because you could potentially receive duplicate content penalties. If you do decide to submit the same article to multiple sites, take the time to change the article title, along with a few sentences in each paragraph to make it unique enough for the search engines.
Make sure you use SEO best practices. Use keywords in the article title, use different variations of the keyword/phrase throughout the content, optimize the url (if possible), deep link to inner pages on your site (if possible).
