Roon adds a comprehensive music exploration and management tool to streaming at the cost of complexity, and sometimes sound quality and added cost. Unless you are interested in mostly exploring music (as opposed to listening), and playing with technology (cause it adds a fair amount of IT complexity to your system) and cost... then using the native streamer software is a much better choice.
Learning, for instance, the Conductor App for Aurender streamers... or whatever the software provided with your streamer will provide great exploration tool that can help you find music... just learn to use them. If really elaborate musical exploration is desired... go to AllMusic.com. or the internet to find music and then use your streamer software to listen to it.
I personally want to listen to music, not go back to being an IT person and get deeply involved in software. Some folks are deeply involved in exploration and software.
