That's a great question Ahmed! Let me brake it down for you.
AMA Submits 2 back links for every article to 2000 blogs. Keep in mind that your particular keyword or article subject may not fit these 2000 blogs so lets say on a good day it fits 1/4 those blogs that's 500 submits of 2 back links for a total of 1000 back links for one article.
FTS Pro works a bit differently they allow 3 back links on 40 blogs (which you select) and 5 extra tag page submissions of the same article. That's 3 x 40 x 6 (original + 5 tag pages) = 720 back links
FTS Free allows 2 back links on 30 blog pages. 60 links.
Will google count all these back links? No probably not. Weather or not your links get counted I would assume depends on the quality of the site they are posted on and how often google crawls that site. I can say from personal experience that FTS has always provided me with sufficient back links to push my pages to google page one. I have only recently upgraded to pro status to start promoting more competitive keywords.
The numbers would suggest that the answer to your question would be to become a member of AMA and keep the free services from FTS. I still say though that I would stick to what works best. Maybe try experimenting. Upgrade to pro with FTS and use it to promote one site and then use AMA to promote another. See which gets higher quality back links and which gets more back links per article.
Expanding your options is always good in article marketing!
I hope this helps - If anyone else has questions I would be more then happy to answer them for you guys!
