Open Graph settings

Our recommendation is simple.. use whichever tool is the easiest for you and covers all the pages you want. You're correct that multiple extensions can set Open Graph tags. There's advantages and disadvantages to each (even JFBConnect). With JFBConnect:
* We'll set the title and description for a page automatically based on the meta title and description for a page
* For Joomla articles, we'll set the Open Graph URL to the best canonical URL we can. That means that even if an article can be reached from many URLs, JFBConnect will use only one URL for the Like buttons or comments, which makes sure they don't get spread out to multiple pages.
* We can set the Open Graph image tags automatically on content pages and we support other extensions.
* JFBConnect lets you set Open Graph tags on a per-page basis using our easy-tag system: {SCOpenGraph image=<link to image>}

That's a quick summary of our features. You know your site and how you want to administer things though, so it's best for you to choose the solution that works best for you.

Thanks,
