McGrath - It's the considered opinion of many in this country that our national anthem has an awkward melody. As a matter of fact, some music educators refer to it as an example of awkwardness. I disagree that it's no more difficult than the other anthems you mentioned, or that a change to America The Beautiful would be a dumbing down. We sing the Star Spangled Banner every month at our chantey sings, to open the second set. We always have to pitch it very low, so that the high notes can be reached by everyone. My belief is that a national anthem should have a melody that's both interesting - not overly simplified - and easily singable for its citizenry. I think the other ones you mentioned fit that category, as does America The Beautiful.
