Looks like Denso is better, some notes on them on Camaros here:

Denso is stock in some GM cars...
"The Denso "O2S" is better because its aluminum-oxide "trap layer" covers the sensor element and resists damage to its platinum electrode and a porous, PTFE (Teflon) filter on the sensor's atmospheric side prevents moisture or contaminants from degrading accuracy."
Top is Delphi, Bottom is Denso:

They aren't the same part. They have different length tails on them.
As far as not giving codes, I have been able to run the Delphi O2's without insufficient switching codes, although I would get the code with brand new Densos. As said above, if you order an AC Delco replacement nowadays you will get a Denso. Most don't care about that code and just turn it off.
Haven't used a Bosch on my car.
