Same here. Just go with EzineArticles cos i they have good quality of reviewing the articles being submitted to them. So articles coming from Ezine are best quality of all.
I think Ezinearticles.com and americanchronicle.com are the best websites for submitting your quality articles
Ezine is good but difficult to work for beginners.. I use few article directories they accept your article within 2 days and make fast traffic. After two days you can see your article first place in google result. http://www.goarticles.com http://www.easyarticles.com/ http://www.articlesbase.com http://www.amazines.com/ http://www.articlerich.com http://www.articlesnatch.com
Another vote for ezinearticles here. It takes around seven daysfor your article to be approved butthe sooner you get submitting the sooner you will be approved. They can be a little strict as well but you'll get the hang of what they want after a few submissions.
