Bosch o2 sensor for DSM good or trash?

I'm using a Bosch now. Installed it yesterday though so no long run experience. Though a great improvement over a dead o2 sensor. Denso was another ten bucks and only had enough for the Bosch in bank at time of order. Cost 32 for the sensor with 2 day shipping off amazon.com.
 
The Innovate LC-1 wideband uses a Bosch sensor...but I like Denso or Bosch. Rockauto has got the best prices, fast shipping and even comes with a refridegerator magnet! WHOO!
 
I have a Bosch sensor now and my car stutters and bucks, spiked from lean to rich. I replaced the plugs and it is only in closed loop so it has to be the the sensor of MAF.
I have a Denso sensor to replace it now. It was $50 bucks and Denso is the OE manufacturer so your getting a OEM part without the dealer price.
 
I could never get my Bosch o2 sensor to fluctuate like it should. It was always on 100% or off 100% and it would just switch abruptly instead of a smooth transition. I tried two different sensors. HOWEVER, when I bought my sensors, one from a parts store, and one from eBay they both had different connectors than my harness. The little key-spline had to be shaved off to get it to fit. I even tried cutting the plug off the harness and using spade connectors to directly plug into my harness.

I eventually just used my wideband to simulate a narrowband.

Hope your experience is better. :)
