I put my vote in for XDR. I have been using them for several years and really like the sensors and software. I have also used them long enough to answer the real question, what happens when a sensor breaks? Cause they will. All sensors at some point will fail. What I like about XDR is they sent me a loaner sensor and then had my sensor sent back perfectly fixed the following week. The sensors are design to be easily taken apart and the wire which is nothing more than a USB cable replaced. Most of the time when a sensor breaks it’s the connection between the cable and the sensor. Not the CMOS chip itself. So the warranty is a lot less, and for me their service is exceptional.
