I had Sirius for 3 years, went to XM-- (Im over 16, so Stern doesn't really matter) However, the COMedy channel does--Sirius has 2: one adult, other is Jack Benny re-runs, etc. The adult one (the FUNNY one) has talky crap on EVERY day from 4pm to like 9pm... (Jim Bruer, and the Wise Guys --Soprano cast-offs) and it ISNT funny. (also, Sirius has a lunch-time guy on their comdey channel for like 2 hours every day, this ALSO limits actual comedy) On weekends, they have even less standup. XM has 2 adult, one Jack Benny-type, and NO talky crap. Music is close, talk stations are close, now that Sirius got Fox stuff back. Sirius has far better blues channel, IMO--XM's seems like elevator music. Sirius makes a BIG deal out of their dj's---though the music channels have no commercials, these people feel the need to blab like 2 minutes after every other song--drives me fluff'n nuts. I give slight edge to XM
