Yes, flying wings do have their uses. The US mostly used them as stealth vehicles, but the flying wing also has no surface that isn't used to generate lift, meaning there is no surface that just has parasitic lift. You can build very economic planes with the design, but the main problem is that they are absolutely not turbulence friendly, as the wings can't really flex as much as they can flex on the conventional design, since you're housing passengers in them.
For more ideas on that subject, one of the Horten borthers fled to argentina after the war and continued to mees around with flying wings there. He said that, as long as the wings were clean, the subsonic flying wing was superior to any other design due to it just generating more lift. As soon as they got rain or other impurities on their surfaces, the airflow would get messed up though.
So in the end, I'd say that flying wings are an option for Cargo, but not passengers.
