O2 sensors

I know most people will tell me to go with Bosch 02 sensors, but I’m curious if anyone has had any luck with other quality brands like Denso or Walker?
Walker likes like the brand that AB sells.

I have been hearing that many Bosch 02 sensors are bad right out of the box. I need to replace mine so I am going with the Walker brand. They seem to be ok.

I went with Walkers off Amazon when my originals died. They've been great.

Ok that sounds good guys. It will save me a bunch of money too, full set of Bosch here in Canada is insane.

I prefer NTK O2 sensors (#25623 Upstream & #25624 Downstream) but that's just me.

I had to remove the whole pipe/cats to change my O2's(which drops out easily).
I needed the leverage(and heat) to be able to get them out.

Both my O2 sensors have no activity on banks 1 and 2. Is this normal for BOTH to go out? Is there some secret fuse or relay? Also, the weather is colder and my SAI pump does not come on at start up.
