Arnej is probably my favourite. Deadmau5 makes great tunes and he is pretty awesome live with Ableton and his Macbook Pro (woop Mac users unite!!), but he's really cocky.... He pretty much thinks that as long as he has support from big names like AvB he can say or do whatever he likes (see his news article about how "normal DJs" bore him and the time he cancelled his gig with Marcus Schossow), its not right, he's making himself look so bad.
Arnej on the other hand is a really awesome guy - he could do with showing a little more expression during his sets (he looks like a stone figure playing live!

) but his production skills are top notch, his tunes are always a wonder to listen to
