Hi Saverio,
I can’t tell you if it’s more reliable than something else, but that I have been using Roon server on Debian for some months without any issues.
You might want to try in a virtual machine (e.g. in Virtualbox). Simply install your favorite linux distro, some dependencies (smbclient and ffmpeg in Debian iirc) and execute the installer.
You can also install Rock as a virtual machine. You need to create a vmdk disk for the usb image (you find howtos and videos how to do this). Second gotcha is that you have to connect a keyboard to the virtual machine (under Devices, USB,…), otherwise you cannot type anything.
