  Colyn,
  
  I fly the XM WxWorx on a Toshiba Pentablet all hardwired (no Bluetooth
  wireless) in my Lancair IVP (about 500 hours with Wx on board) and WSI
  in the Epic on the Chelton system (160 hours).  I don't think I can
  comment on the quality and accuracy question you are asking.  I can
  relate my experiences flying with both of them.
  
  
  I like them both.  I won't fly IFR without them anymore.  They can help
  keep one out of harms way.  They are both seem equal in knowing where
  you can fly safely and where you should avoid. They are both very useful
  to knowing where you can fly (deviate) to stay clear of weather systems
  or buildups.  Overall the flights are much smoother as one deviates to
  avoid weather.  I would never use either for penetrating a line of
  thunderstorms, nor have I attempted to do such.  They both help avoid
  icing if you stay out of the green.  My wife loves to be the onboard
  weather maven keeping me up to date on the metars, cell movements,
  distant areas of significant weather we are flying towards and what is
  happening elsewhere around the country in the weather department.
  
  
  WSI is more convenient in the Chelton as it is displayed on the moving
  maps, comes on automatically and is dash mounted.   It is more reliable
  in having the data available.  It has only failed to provide data on one
  occasion.
  
  
  The XM WxWorx on multiple occasions could not be used as I could not
  connect and had to call and have the program reactivated several times
  (4 or 5 times), the receiver antenna failed twice and the GPS 3 times.
  In every case XM and WxWorx were very responsive.
