Spotify vs. Rdio

Im finally moving to a streaming service from iTunes. Ive been using the ATT 90 day beats trial but it expires soon. I like beats music but im not a fan of the design. so i am deciding between rdio and spotify. Design is really important to me but rdio no longer has a huge lead in that like it used to. As far as collection goes from what ive heard spotify has a slight advantage but both servics have everything that i listen to. Any help on deciding?
