Silicone Viton or Nitrile for o-rings

I was curious about the different o-ring materials since there are so many & found Chemical Compatibility Guide. Comparing Silicone and "Motor oils" returns "Good" but common Nitrile (NBR) or Viton (FKM) both come back as excellent. I'm no chemist, just passing along what I find. I thought silicone would be better, maybe not? Am I missing something? Just trying to learn something new.
