Why would anyone use `go articles` over `ezine articles` ??

Hi guys,
This is just a question i have been asking myself and wondered what you guys thought,

All it is, is that i never have done article marketing i have always built blogs as my money sites and pages, I have written articles but just for the backlinks to my blogs and not as the sales page.

But i have been thinking about using article marketing and writing a few great articles written for sales with an affiliate link and see if i can create extra sales as it can take a while for me to set the full blog up backlink it to a good position in SERPs and make any money.

So i feel i could get a few articles up with affiliate links in no time at all, But i am just wondering why i see so many marketers talking about using `Go articles` instead of `Ezine articles` ?? Yes i do know it takes much longer to get the article approved but isn`t it much better to have a article sat on Ezine than go articles ?? or is there another reason ??

Also i have read that go articles is taking a very long time to get articles indexed as google has lost trust in them at the moment ? Is this still the case, Has this ever been the case ? And how is go articles now with getting your artcles indexed ??

Thanks guys.. Jim
