Another aspect is the ability to see comments custom-tailored to you. So your Best Social Friends comments will be visible to you on the top irrespective of the fact that when they were posted

Even though this is common place now and not a very big deal , but being able to reply to specify comments is always a great UX move. Considering just last year it was introduced in Blogger officially , its pretty big deal that its inherently present from start in this comment system. It gives more organized feel to your comments sections and makes it many times easier for you to manage the comments.

If you are a Blogger user , then you will not have to worry about losing all your previous comments that your blog received till now as all those comments will get automatically migrated as-and-when you choose to switch to Google+ Comments and reverse will also be possible soon if you think of switching back to the old comment system .
