Thank you. I am also quite capable of using the forum and posting there, and have done both. If you yourself of were to check it it out, you would find many Roon users disappointed with the search compared to J River - you are restricted to a small number of tags, you are restricted in the way the results are presented, there are no logical operators or their equivalents, you can only filter once..., you will also find folk who prefer to do their searching in Qobuz and only use Roon for playback, and you will find plenty of complaints about the way Roon mishandles boxed sets, another area where J River has advantages.
I’ve said before that Roon now suits my needs more than J River, but that doesn’t mean I am an uncritical fanboy prepared to gloss over its shortcomings. I would say that if you don’t use a streaming service, and you can live without artist bios, but you do want to organise and search your music the way you want rather the way someone else forces you to, then J River, foobar and quite possibly iTunes are better value and better products.
