Default AC Delco Oem Vs Professional

What is the difference between the Acdelco Oem Vs There Professional series brand? I'm looking to change out my o2 sensors again because I have Bosch on it now and upstream falied then later on the down stream. Barely a year since I bought them for it. I'm looking to go with ac Delco and would like to know the difference between there two parts. Thank you.

The Professional Series has a longer warranty. I think it's 24/24,000 instead of 12/12,000. Given what happened to an OEM plug in my wife's Caddy, to say nothing of the OEM rotors on my Aurora that warped after less than 10K miles, I'd go for the higher warranty.

ACDelco also does outsource production of some of their products. So the 2 versions might even be made by different companies. I concur, if the option is there, I would lean towards a professional version.

I was looking more towards the professional myself, could not find much on Google, ran across alot of there videos though. I need to plug a hole on top of my catlyic converter too, it's popping up the old po137 code plus the 171. Figured that exust leak might the reason the plug might have went bad too.
