Ordered A/C Delco NB O2 Sensor

There's been a lot made on this forum regarding the difference between Bosch NB O2 sensors and the OEM GM sensor. I suspected that my NB sensor may have been poisoned by some O2 sensor "friendly" sealant so I ordered a new AC/Delco O2 3-wire. Came in an AC/Delco Box. Had the Bosch logo on it. Bought it from GMPartsDirect.com. WTF?! SO is there really a difference?
