The backing beat gives a feel that these two are standing atop a stage with a DJ while they look at each other trying to keep going. Listening to Jakobe he has a great voice for doing this kind of a vocal battle. Sadly Klazik kind of sounds like he was being random and disorganized with what he said which didn't flow well with the beat and just sounded pretty bad sadly. Should work on rhyming skills and come back the next time.
As for who wins overall, Jakobe without a doubt. For KlazikNadi, I recommend doing some more practice and then trying again.
