I use and love it in all of my cars. I have Spotify and Apple Music too, but there's something about actual "radio" without commercials that I enjoy for longer drives.
Sirius is the only decent music discovery service for me since there's some actual human curation going on (at least on their main channel lineup). Spotify is nice when I have playlists prepared and ready to go but that takes work and I get tired of most of my playlist content after a week. Discover Weekly is garbage, and Google Music's version was far worse. Never tried Apple music.
But I've also noticed the repetition on SXM but I've settled on 3-4 channels I like so I switch between them to combat staleness.
