There are quite a number of free third party commenting systems available online and there is always a dilemma over which one to choose.
I was also confused but decided in favor of Disqus and here are some of the key points that I considered before making a decision.
You may also find them useful to decide for you:
|Corporate Networks||Not Blocked||Mostly Blocked||Disqus comments are usually NOT blocked on corporate networks but Facebook, being a social network, is.|
So, you may loose a substantial comment activity when user accesses your web page from their office network.
This one was one of the biggest con against Facebook comments for me.
|Google Indexing||Indexed||Indexed||Google indexes both comments systems now.|
|Log-In Options||Multiple Options||Multiple Options Except Google.||Disqus allows a user to log-in via multiple open social supported platforms like Google, Yahoo, Twitter etc. including Facebook.|
On the other hand, Facebook comments also supports most of them except Google!
So, given the popularity and the registered population of Google, it is a big miss.
|Import / Export||Available||Available||Disqus and Facebook both allows you to import/export comments from their system, in case you decide to move to a different commenting system in future.|
So, you can pretty easily export your existing blog/web-site’s comments to Disqus without loosing them.
|Moderate Over Email||Available||Not Yet||Disqus comments allows you to ‘Reply’ and moderate via email too. You would receive an email when somebody leaves a comment on your web page. Just reply in the email with the answer and the ‘Reply’ comment will be instantly available on the web page where it was left by other person.|
The moderate comment command are also available like ‘Delete’ to delete the comment.
On the other hand, you don’t have this feature on Facebook comments yet.
|Changing the Web Page URL||301 redirect Available||301 redirect NOT Available||I tried hard to find this one but could not find for Facebook comments. When you change the URL of your web page for some reason, you most certainly would like to re-direct the old URL links (In Google index or other places) to the new URL by using a 301 re-direct to keep the page rankings intact.|
But what about the comments? Facebook’s comment system is based on URL and if it changes, it won’t be able to use the re-direct automatically. Will it? As far as I know, it does not support it currently.
If it is, please help me with the answer and i will be happy to update this section.
You have a hack though where you can use the old URL in comment box to keep the comments and count intact even after redirect.
On the other hand, Disqus has the facility where you can re-scan all your links and it will automatically map the old URL comments to new ones.
|Monetization||Available||Not Available||Disqus allows you to place ADS on the comments and pay you the money when users click on them. Facebook does not have this system.|
|Traffic||Good||Good||Both systems bring good traffic. I like Disqus more just because it promotes your own posts with more comments automatically. Visitors are more inclined towards reading more articles and stay more time on your website. Facebook comments does not seem to provide this feature.|

Ultimately, I decided in favor of Disqus as you can see on this blog. I hope the above points would help you take a decision too.
Don’t worry if you are still confused, you can pretty easily use both systems on your web page! Yes, just add both service’s comment box code and you are done.
But then, you will be confused about which one should appear on top of other?
Just a suggestion, place them horizontally to avoid any further confusion and delay 🙂
