lk63 came with more creative rhymes and references, and except for that weird "I ain't got enough guts" line, it was pretty solid. Gibberish stayed the whole time at the level of "I'm MC Rapper and I'm here to say / I'm the best emcee in the USA" -- that kind of basic stuff. Utterly uninteresting except for his use of the word "charisma". My (unofficial) vote goes to lk63.
