I used Roon for a 30 day trial and chose not to stick with it. It is an attractive program in many ways for organizing and exploring one's music collection. However, I actually found it frustrating since Roon doesn't have an option to explore my server's folder setup, which is my primary method of organizing my music. They want you to find music their way and to hell with the way you used to do it.
Also, I am very happy with the way Qobuz lets me explore new music and material I don't have in my own collection. Roon didn't improve that experience for me.
All in all, it just wasn't worth the cost for a few bells and whistles, and it went backwards in areas I wanted to keep. However, I know a lot of people who love Roon, so this is a decision only you can make for yourself.
