It seems to me that the main benefit is that it takes care of parsing out the template parts around the expressions for you. Otherwise you might write a regular expression to do that.

It seems to make certain specific function calls look very different from a typical function call, the arguments passed in are not very clearly explained in the draft or wiki, and I have difficulty imagining anyone actually using these for anything. I would love to hear a solid case for these (I've been looking for the past few nights, but nothing has shown up). Template literals are great, but the `tagging` thing seems fishy for the vast majority of applications.
