I came to say the same thing. This option works great.
You can embed your comments as needed... customize / configure Discourse as needed... it's easy to work with (even across pages hosted on different URLs -- if you can set a Canonical you can call the right comments)... easy to add signups to your CRM... my clients running this setup have been very happy with it.
Disqus... you leave the site, you leave the branded design, to create an account and sign in... it's trash for real sites.
GitHub... seems like shoehorning in something not quite right. "Paint the cat orange and call it a tiger..."
