There is a useful tool called (IIRC) a PMI chart, where you list plus, minus, and interesting differences. I find it useful since not all differences fit neatly into plus/minus categories.

My personal list would be something like this:

950 vs RCVR

Plus:
  • DTS-ES discrete
  • separate adjustable crossovers freq for mains, center, and surrounds
  • Decoupled processing from amps
  • Analog bypass for stereo two-channel inputs
  • 5 year transferable warranty
  • on-line community of users
  • manufacturer that works hard on customer service


Minus:

  • No up Conversion of S-Video to Component
  • No THX decoding (a variation of Dolby Digital / Dolby Digital EX)
  • No autoswitch between a digital signal and an analog signal
  • No 7.1 preamp inputs, just 5.1


Interesting:
  • No DSP modes (not important to most)
  • Limited analog bass management on 950
  • No THX certification (may or may not be important)


Or something like that.
