In this post I have made a list of best and most popular WordPress blog comment systems which you can enable for various reasons like stopping spam comments, increasing the number of discussions, to provide a user-friendly interface for commenting to your users or to let users directly comment on your blog from their WordPress account, Google+, Facebook or Twitter account.
1) Jetpack comments: I highly recommend Jetpack comments. Currently, we are using Jetpack comments in all of our blogs. The best part what I have seen about Jetpack is that it literally stops the spam comments. From the day I have installed Jetpack comments, I have never seen a single spam comment.
You would need a WordPress.com account for using Jetpack. Users can post comments by using their Name/URL, WordPress account, Twitter account, Google+ account, or by their Facebook account. You can read one of my posts where I have mentioned the advantages of Jetpack WordPress plugin.
2) Disqus: My second best choice for blog comment system would definitely be Disqus. If you want more comments on your blog, then Disqus should be your number one choice. The reason is that most of the bloggers use Disqus in their blogs and people have a habit of that. You can create an account in Disqus and it works more or less like a social network. They also provide you a profile in their site where you can track your comments, followers, following and upvotes. For Example, here’s the Disqus profile for this blog.
Readers of your blog can easily post comments by using their Disqus account. They also have the option to post comments using Facebook account, Google+ account, Twitter account or by using their Name/URL.
Another advantage of using Disqus is that, you will get more referral visitors to your blog arriving from the Disqus profile page. If you have already installed Disqus in your blog then, you can track the referral traffic from Disqus in Google Analytics, by following these steps:
i) Login to your Google Analytics account.
ii) Go to: Acquisition –> Social –> Overview
iii) On the right side, under social network you can see the referrals arriving from Disqus.
Disqus has many advantages, but I am still skeptical on using a third-party comment system on my blogs. The reason is that I have seen many people have reported ads popping up in the Disqus comment system. However, to remove ads you can try Scott’s method.
3) IntenseDebate comment system: IntenseDebate Comments is yet another Automattic product. (people who created WordPress and the Jetpack comments system). IntenseDebate Comments promises similar community features like Disqus. The best part of IntenseDebate comments is that even if it is a third-party comment system, you can still disable it anytime. All the comments are stored separately as WordPress comments, and when you disable it, comments will still be displayed as WordPress comments.
Here are the features of IntenseDebate comment system:

vi) RSS integration: IntenseDebate comments are integrated with Bloglines and Google Reader.
vii) Gravatar integration: IntenseDebate comments is fully integrated with Gravatar.

There are some unique features in Livefyre like Facebook and Twitter integration, embedding media in comments, comments editing option, displaying live commenters, and letting users post comments by their LinkedIn account, or with OpenID.

vi) Comment subscribers: You can display the number of comment subscribers for a particular comment. This encourages users to post more comments.
vii) Edit comments: One of the most unique features of Livefyre is comment editing. Users can edit their comments in Livefyre.
5) Vicomi comments system: If you want to display emoticons in your comments then you should try Vicomi. Vicomi is a responsive and adaptive comments system where users get points for posting comments and for other actions.

I like Disqus and comment luv the most, but we usually do not get any SEO benefit out of them. For SEO purposes, wordpress comment plugin is the best to get the website URL indexed in search engines.
I like intense debate comments and I use it for SEO purposes all the time.
For SEO purpose Disqus and Intense Debate is good. Links are crawl quickly on these comment plugins.
