I don't know if one brand is really better than the other, but the ACDelco and the Denso sensors are similarly priced, and both are pretty popular for our cars.
You probably only want to replace the o2 sensor in the front, as the one in the back doesn't affect performance at all. The rear o2 sensor is only there to make sure that the catalytic coverter is working.

Why do you think it's the 02 sensors?
IF you are throwing a P0420 code and AutoZone is telling you 02 sensors, it's not, it's your catalytic converter. Been there, done that, had mine replaced free because a lot of the '01-'02 models had a faulty cat. https://montecarloforum.com/forum/monte-carlo-repair-help-8/cel-code-p0420-1794/

Well my catalytic converter basically went out so I had to get tht replaced but in the process of getting the money for the catalytic converter I think one or both of the 02 sensors went out. The guy did the diagnostics and told me I need to get the 02 sensor fixed but he didnt say which one my dumbass didnt know there was 2 so I didnt ask ha. But my car stutters at times and doesnt get up like it should(only in the day time tho?) so I wanna get it fixed asap. I live in Az too so its so hot!

Okay, now let's do it this way.
If you haven't replaced the catalytic converter yet, I would purchase this downpipe. This will give you a new high-flow catalytic converter, fix a large exhaust restriction, and get rid of the horrendous u-bend that "protects" the rear o2 sensor.
Now without knowing if your O2 sensor is bad or not, the rear one JUST reads the cat, so if the cat is bad then that sensor could read poorly, I can't help you on that front. But if you REALLY think you will be replacing a sensor, I would buy it prior and bring it with as a dealership will charge your $140 for an O2 sensor.
