I think it depends on the channel too. I've read the low number channels get more bandwidth and the channels above 300 are a newer more efficient codec that not all radios support. I've also read the Sirius version is worse than the XM version. Yes, they merged many years ago but they still run two incompatible systems. Ford was still installing Sirius until 2021.
