I think WP's comment system is still pretty good. They talk about Disqus support being being unhelpful and yet chose that as a platform, which makes me really wonder if it's a good choice.

I like this post on WP Beginner about Disqus - http://www.wpbeginner.com/opinion/switching-away-from-disqus-review-increased-comments-by-304/
