I have posted 8 articles on InfoBarrel while I have also posted 49 articles on HubPages. HubPages outshines Infobarrel at this point.
You can post more pictures with slide shows. You have the Hubpages program to earn revenue in addition to Adsense, and you can wind up using Google Analytics faster to understand your strengths and weaknesses. You must post at least 10 articles on InfoBarrel in order to use Analytics. You can link with other HubPage articles without restriction. InfoBarrel is very limited - it's limited to 2 or 3 links.
If you are starting out, I would definitely recommend HubPages. If you become successful in developing a following, you might consider moving on to InfoBarrel. I am not trying to discourage you from InfoBarrel. I am only telling what I have found out objectively through experience.. InfoBarrel has been around for awhile and has a great following.
