This arpeggio is really amazing sounding in my opinion, and its very refreshing to use these Major seven arpeggios if you are normally using the traditional triad arpeggios. Theres absolutely nothing wrong with triads, I use them all the time, but its a question about what sound you're after, if you want Neo Classical Metal or Shred guitar then the triad arpeggios are perfect, I might also add a Dominant seven arpeggio to a Neo Classical Metal piece of music though, but thats pretty much it in most cases. But if you want more contemporary Shred guitar I really feel that these type of arpeggios add so much fresh and new to the sound. Happy shredding !
