Serena's got a pretty kick-a$$ voice, and her vocal gymnastics are pretty outstanding. But the ego definitely bugs me. I'm a Harlemm die-hard, and I'd like to see the two of them go at it in the last round, with Harlemm crushing the competition.
But on a more realistic note, the world already has 1000 Serena Henry's, but has there ever been anything like Harlemm before? Give Serena a record deal and she might release a middle-charting single or two, but ultimately she'll get lost among all the other R&B divas. Give Harlemm a chance, and the worst that could happen is that the world might not be ready for someone with his mystical draw--but on the other hand, the upside is that he might be the most unique and amazing thing the American public has seen in awhile.
