They are both Bosch sensors however the VW one is slower to respond.

So is it worth the extra $$ for the difference in reaction time, for datalogging?

I have the VW, I get pretty awesome logs so it is at least fast enough for the UTEC logging rate, lol

The faster response is evident if you run the two side by side and have a rapid change of AFR.

Fundamentally the original Bosch sensor has larger holes than the VW sensor. Of course you may wonder whether changing the hole size would improve the response. I'll leave that as a thought experiment for the gentle reader.
