I've only had the chance to test two, but under extreme duty the PLX devices wideband stood up to the most abuse. I had it installed in my offroad car when I took it to the desert and it took every bit of dirt, debris, high ambient temp, and hard impact without a single problem. A couple months ago I was driving around, and the control box slipped between the seats and out the bottom of the car. I DRAGGED it 5 miles on pavement before I realized what happened... It still works fine!
The Innovate lasted only 2 weeks in a friend's off-road car. One hard hit, and it was done. He's very unhappy with it.
So there's my very odd 2 cents.
