Default Rife sensors

Curious if any of you have experimented with them vs the fairly standard GM sensors used in aftermarket EFI systems? The claim is that they're faster reacting and more accurate. I have experimented with them some(IAT sensor only so far), and haven't really come to a solid conclusion yet. They are not exactly plug and play for Megasquirt (the ecu I use), but are for Holley, Haltech, and Fueltech. They come with a 32 point calibration curve that isn't easily adapted to MS(but can be done). With some help from Matt Cramer at diyautotune, it was verified that the MS 3 point curve generator was .3 average off of the 32 point curve, so basically close enough for testing purposes. And MUCH easier than (someone like me) trying generate the custom files to use the 32 point curve. Curious if any of you have used them and have formed a definitive opinion of the claims of faster response/better accuracy?
You can follow my path to testing side by side with the GM sensor and a datalog, here:

If any of you use MS/Megalogwiewer, I can send you the logs for your perusal. I have a log from key on cold through fully heat soaked, but it's too large to post.

Including a pic of the side by side sensor arrangement, just cause...
