I think some of the differences in a non-adjustable algorithm will always be there as our expectations of radio stations are different.
I would prefer silence to having to listen to a station that stayed inside one genre and had a tiny artist choice (roon radio V1). I like radio shows such as radio paradise or the blessed John Peel as was. (roon radio v2)
If you just listen to Rock FM then you are going to hate a mixed play show and vice versa.
As has been mentioned by a number of people a dashboard of sliders to adjust the radio (and generated playlists) would be an idea. Such as delivered in Music IP https://www.spicefly.com/article.php?page=spicefly-sugarcube-settings which allowed you to set your randomness, repeats, jaggedness of the genre change, etc etc. to generate playlists from your library.
