My perspective is that Roon's strong point is information about the music you are listening to -- who was the drummer on that album, and where can I hear more of him or her? Roon also claims the ability to introduce you to other artists similar to the ones you already like. If you like these features, you're probably a Roon fan.
I tried Roon and found I don't really explore music in the way it offers. I haven't found myself particularly entranced by the musicians themselves, and often found the "similar artists" Roon recommended just didn't do much for me. Yeah, the styles may have been similar, but the new-to-me artist frequently just didn't grab me. I have a Qobuz subscription and have a lot more fun exploring their new releases every Friday -- I've found more new-to-me interesting artists that way than Roon ever did, often in styles and genres that have zero relation to anything I've been currently listening to.
As is common in the audio hobby, YMMV. Use what works for you.
