I don't doubt for a second that, from a sound perspective, TAS/XDMS outperforms Roon.
From what I have read previously, a lot of work has been done around Roon as well.
Which is also a very good thing and quite an achievement!!
Unfortunately, as far as functionality is concerned, XDMS will not allow what Roon does and that made me choose it a few years ago. I talk about it here:

Having both, and choosing according to our desires, is also a good thing. Browse the library or have an immersive listening.
Anyway, at the moment, I wouldn't be able to compare anything.
My system is in my office and the listening room is under construction.
