Scrum meetings - By developers or user stories?

What is effective in Scrum meetings? Going over by user stories (assigned for that Sprint) or going over by developer?

In the case of user stories, you go over the all the user stores assigned for that Sprint, check the status with the developers & QA assigned to that user story and identify any blocking issues.

Another option is to just go from one developer to another and ask him what he is working on.

I feel doing scrum meetings by user stores is more effective as it helps to track the story better and identify blocking issues. Just going over what developers are doing one by one doesn't convey the whole picture..
