@mdrone I think this issue mostly is software evolution, not problems with Roon servers. Roon tries to do a major release 2x/year, more or less. Some releases have had bugs quickly fixed. Other complaints have often been some users preferring old look, etc.
Overall, IMHO, Roon has done a better job than many software companies making mostly good decisions about what new features to add first, etc. There's certainly plenty more to do, but I feel their track record points to a reasonable likelihood that it will continue to be the best overall option in the market.
Some releases do require the server companies to make updates. A handful of companies have proven to work quickest and most effectively with the Roon team to minimize issues. For example, quoting from Roon's own forum about their last major update:
I'd give serious consideration to running Roon Core on one of the products from these companies. In my case, SGC has worked great and when I had an issue, received superb support to resolve it, even though the problem was a Roon setting rather a problem with the server. Cheers,
