The lowdown on widebands?

I?ve been looking around in the forums and internet on the topic for a while now, and was wondering if someone could give me some more info on widebands.

So essentially, are there pros and cons, similarities and differences with Lambda vs AFR?

I’ve seen all the Bosch 4.2 and 4.9s, along with NTKs. What’s the ideal sensor in terms of cost and performance? I’ve read the NTK is relatively more durable than Bosch and that it’s actually considered “lab grade” but that’s all I’ve really gained.

What about the best brand/controller/gauge on the lower prices ranges
I’m aware of AEMS, Ballanger, NGk, PLX, etc but haven’t really seen any clearer answers which would be expected as I’m sure they are all good in many ways?

Lastly, and a bit more specific, if I want to utilize a 14point7 unit, what’s everything I would need to put one of those together? Like what controller board sensors etc?
If there’s a thread that covers this entirely or just one of my questions, would be greatly appreciated to be able to see.

I've never once had a problem with the AEM widebands using the 4.2 and 4.9 sensors. They are very accurate for what they are.

I can switch either to be using Lambda or AFR. For most it's all a personal preference but Lambda is generally easier because Lambda is Lambda is Lambda if you get what I mean.

If you plan on doing many cars, especially power adder/methanol, etc. Go with ballenger in a ntk sensor. AEM x-series are fine for light duty use. 14point7 seems to be good so far, i have duals on the dyno.

If any part of your first sentence was true you would already have your answers.

I’m also relatively interested in personal experiences with such, not just data

My AEM went bad in about a year. I don't like them, but it's cheaper to keep putting sensors in than to buy a new unit from someone else. Bosch O2 sensors, narrowband and wideband, are garbeege.

As far as gauges, I prefer AutoMeter.
