That's been my understanding for years now. You'll pay an extra premium for AC Delcos and get Densos. Densos are as good or better than anything else out there. I use them and have been relatively happy given all the issues that LT's cause for O2's.

Delphi is a bunch of "bad GM" that GM spun off a few years before it went bankrupt in 09 or whatever it was, when they got rid of a bunch more of that by that means. The AC/Delco division was/is the core of it.
AC/Delco is nothing but a brand name nowadays, which now belongs to Delphi. The part that comes out of the box could have been made by almost anyone.
Never heard of NTK.
Bosch owns the patent on the O2 sensor and licenses it to everybody else.
I feel TOTALLY comfortable using any OEM grade part of that sort. Much like spark plugs. Denso is in that category: they're OEM for some of the Japanese car mfrs. Given how generic the operating principle of that sensor is (again, much like spark plugs) that would be a good choice. Oxygen behaves chemically the same in a Honda, BMW, GM, Frod, or any other brand of metal.

I went with ac delco and had no issues. On rockauto they were only a few dollars more than the bosch and there are plenty of stories about bosch being hit or miss on ls1 motors.

NTK is a high end component, NTK/NGK. Most top tuners prefer NTK widebands...which we aren’t discussing widebands here...for tuning. My NTK wideband cost over $500...just the sensor. It’s a laboratory grade sensor. Accuracy is key.

I've used Bosch O2's many times with various cars never had any issues. Only issue I've had with Bosch was an ignorant person at an auto parts store got very upset I was using "German parts" on an "American car"
Also had excellent results with Denso. I think the Denso O2 was like a millimeter shorter and fits better in a tight set. Also easier to thread in on the first try due to the tapered first thread. Denso also includes anti-seize with each O2.
I really like Denso

Denso products are excellent.
But with all the brands listed you're splitting hairs. They're all great. Not one really any better than the other. I will say this though, always go japanese if you have the option to.
If you can get two denso's for $50, do it.
