XM, an early lead
A serious question is at hand here. Going with one provider commits you to a significant investment that would be costly to reverse. Both charge the same amount for activation ($10 online and $15 by phone) and monthly fees are constant at $12.95 per month, payable yearly if you choose. However, in the first of very few distinguishing characteristics, Sirius reserves the right to charge you $75 if you cancel before a term has expired. XM will pro-rate your payment if you cancel.
That said, the smart money is still on picking the one you like and sticking with it. Sirius satellite radio has a slight edge in the talk radio department, boasting NPR Now and NPR Talk. Sports are strong as well, Sirius has exclusive rights to the NFL, a wide selection of college sports, and plenty of talk options.
Upon comparison, the differences become even more minute. XM has been noted for producing sound a hair better than Sirius. They don't have football, but they do carry rights to pro baseball, golf, and NASCAR. And while Sirius offends with Howard Stern, XM does it pretty well with a couple of new guys called Opie and Anthony. Any receiver specific to XM will have a virtual twin made for Sirius. An advantage could be seen in XM's status as the market leader. With a few million more subscribers, they may have the clout to drive Sirius under.
Music is a draw
Of course, what's most important is the music programming. When asked, most people enjoyed the selections of both, for they are nearly identical. Jazz lovers love to listen to varied jazz without interruptions. The same goes for 70s rock, folksies, and 21st century hipsters. Rest assured both companies have ample options.
Finally, it is worth noting that radio marketing execs still can't tap into a subculture and present their music tastefully. I may love Art Blakey, but I'll wait till home if I have to hear him on a show called "Planet Jazz." Intelligent, song-writing, guitar beaters are promised on a show entitled "The Loft" and countless other programs occur in some sort of "Café." But square as they may be, those execs have put together a good product.
