David Guetta vs. Bassnectar: Who is Better?

I was watching new music videos on Vevo on my iPad last night and came across two new electronic songs by David Guetta and Bassnectar (feat. Lupe Fiasco). Each of them have their own own unique sound and visual style. As I was watching I couldn't decide which one I thought was better...

...So I am leaving it up to you! Which song do you think is better based on the music and video; The Alphabeat by David Guetta or Vava Voom by Bassnectar ft. Lupe Fiasco? Comment!
