I believe that Motorcraft sensors are just rebagged NTK sensors.
SNG and OMIX sensors might also be available.
Conventional wisdom says Bosch sensors are crap.

Those are the 2 that are on the shelf around me,most of the time. A friend went with bosch. I thought Denso would be the better choice. It was his f-150. I was only a helper that day.

Our failure rate at the shop with Bosch O2 sensors was way too high, switched to Denso and problem solved. In cases where Bosch is the original O2 sensor then going with Bosch is ok as long as you get the OE one but keep in mind that the Bosch sensor you get fromt he parts store may not be spec'd the same as the one you get from the dealer.

Scott,
that is the issue in my circle. The off the shelf bosch have failed, a few of us. Those that switched to Denso, no problems. I replaced the ones on my '88 302 t-bird with AZ bosch. They seemed to be lazy. Way too rich on start and warm up. Went to the dealer, bought the motorcraft, all was well.
My buddy's '04 f-150 4.6L bank 1 sensor got lazy at 185K miles(wore out). The parts store denso's were $4 less than the bosch. His thought was, he never heard of denso, so they must be cheap...LOL.
His $$, his truck......
I thought the hi/low voltage specs for the feed back loop, is standardized. Just for my info what specs' are you refering to?

Eddie,
In alot of cases the heater resistance of the O2 sensor is different which in turn affects how hot the senosr gets. Obviously if the sensor is too hot or too cold it will read differently and therefore can affect mixture. Usually if it is way out of whack it will throw a heater circuit code but not always.
Wait until you start messing with Air Fuel ratio sensors, which is the way everything is going. They look exactly the same but operate completely different and voltage is anywhere from about 2.5- 5 volts depending

I bet that will be another code to break. So performance tuners tuners can over ride it......LOL
I have read that there are alot of states. That try to pass legislation every year. To shut down the performance aftermarket. Including performance mufflers. So far the aftermarket lobbist have been successful. To stop the legislation.
You probably remember a few years back. The auto manufactors were trying to pass fedral legislation. That would have put you out of work.
