Or you can have the car tuned SDOL (Speed Density Open Loop) and get rid of the O2 sensors. This is how I did my heads/cam LS1 in my trans am when I had it. Made life easy.

In the "parts aftermarket" world the "BOSCH" the get by and price point line. Quality is not so good long term.

AC Delco units "for GM vehicles" is a quality part.
Most GM OE are manufactured by Denso, NGK & Bosch.

Understand the aftermarket division quality is very different than than that of price point aftermarket.

It depends what your long terms plan for the car are. If you are planning on staying stock or close to, nothing wrong with Delcos. If you plan on modifying I.E cam heads etc, cut the loss and tune for open loop speed density. Just my two cents.
