If you're duping an article that's already on your site, you might not receive any credit for the link. In general, I'd suggest not syndicating any content that's on your site, period. You might find your own pages going supplemental.
Link benefit you receive will also hinge on the kinds of sites that use these articles and the kinds of inbounds the articles get on these various sites. Chances are that sites which use articles from article sites are not likely to be very high quality.
I'd also suggest that if you have a lead on a high quality inbound link source, it's possibly worth creating a unique article for that site. Links from dupe pages are very possibly going to be downgraded.
