If you are happy with the iTunes interface, Pure Music uses the iTunes window as your interface (even though it completely takes over the audio section) I'm happy with Pure Music and your Apple Remote app will control the music from your phone or pad. Don't know how it stacks up sonically, but it is very seamless and easy to use since it looks like iTunes with a blue box in the upper right quadrant for Pure Music.
I really like the JRiver display, but you won't find it particularly easy to navigate if you have been a devout iTunes user. You'll figure it out, but somethings will be frustrating for a moment or two until you have that "AHA" realization.
