OEM or Aftermarket O2 SENSOR?

[CiVeK9]

my check engine light is on for a O2 Sensor. I forgot if it was the upstream or the other one. Hopefully its the easier of the two. I'll have Autozone rescan my car and tell me. But should i go oem which is over $150 or get an aftermarket one from Autozone? I think they only run like $50-$80
