Hi Mark,
Thank you for your inquiry. To be honest, if you just looking for plain commenting system, EasyBlog's native would suffice. However, should wish to have a much more powerful commenting system, I'd highly suggest for you to consider Komento. Few of Komento's extra features are :
1. Komento has live notifications for new posted comments (if you are currently on the same page)
2. Location tagging.
3. Komentto supports and allows attachments.
4. Komento can be used to support other components as well. This is an excellent solution should you prefer to have only one commenting system for your whole site.
I hope my answer helps to understand Komento better. Do let us know if you have any further inquiries.
