Well, I have been using the cheap aftermarket Bosch sensors. However several other boards are having discussions and several people report going back to the Delco's have solved problems that they had while the Bosch aftermarkets were in.

I wouldn't use the bosch in a stock application, however it appears bosch vette rears work well in Long Tube applicaions.

So from the factory do they come with AC Delco? What about the Denso brand?

I bought a set of used vette rear O2 sensors and they work good when I'm driving but when I'm idle they don't look right to me. They don't have a true swing back and forth and look kind of dead. I wasn't sure if that was because they were used or because they were technically rear (dummy) O2 sensors?
