When I had sling the audio would lag very badly. It also took longer to set up. Hava has better picture quality period. If you look at the specs it will stream in a higher rez. They do have some issues to work on for remote quality and the mobile player but this can be fixed via firmware update which will hopefully be soon. Take a look for yourself
