Default delco or bosch 02 sensors?

i originally placed this thread in the tuning section but i think it would fit here better, so here it is.

i was wondering if the tuners here have had better luck with the bosch or gm 02 sensors? i will be buying new ones and i am not sure which ones to go with. by the way, my car is modded with full bolt ons, cam, heads, etc.

either will work... O2 sensors are like hit or miss but normally everyone has their preference and sticks with it... a lot of people will bash bosch products but support them mostly as I have never had any problems but as well you can't go bad with GM products... a lot of stock GM parts are from bosch too

As of today AC Delco sensors are made by Walker, you never know. Low bid wins. This sensor looks different from yours (the part that is in the exhaust stream) but a lot cheaper, it fits the Trail Blazer SS, PN 12604913, list price is only $60.00 each. Yours are between $146 and $151 each. The work great for swaps, I have them on mine and so far so good. They are 400mm long so the have some good reach to them.

yeah i have noticed the newer bank 1 sensors from gm have more circular slots in them instead of the standard vertical slots that you see in most standard sensors. i have no idea why though.
