Go have a look and see if you can find the stuff you want now, to check it out kind of. Not sure if you're aware of how RS works, but you cannot browse through RS's databse to find items. You have to find links posted on websites, forums, given to you by people directly perhaps, or by using RS search engines.
I don't think one is necessarily much better, though there's pro's and con's. e.g. Usenet, nothing is ever deleted, but you are at the mercy of your providers retention (given that Astra has like 400days+ that's not a biggy imo). Rapidshare, stuff is often deleted, but some files can last for ever (they usually don't).
If you want TV shows, movies, music, games, both will probably suffice and I reckon sooner or later everything mainstream pops up on both. The groups release most stuff on different mediums at the same time and 3rd parties also upload what they got from a torrent to RS or Usenet sooner or later.
Me, I prefer Usenet somehow, maybe get a short term subsription to both and see how it goes.
