In theory Zigbee has more range, but in my limited experience it's only slightly more than Bluetooth.

I'm not sure about durability. Both seem to be intended for indoor use only.

They both use a CR2032 and I haven't had them long enough to see a battery die. I'd get some warning with the Bluetooth sensor because it reports battery level.

For precision, the Zigbee has a wider range but less precision: -20 to 50 C at +/- 0.3 C vs the Bluetooth 0 to 60 C at +/- 0.1 C. For humidity the Zigbee is +/- 3% while the Bluetooth is +/- 1%.

There are pros and cons to both, and the best choice depends on your own circumstances and needs. I think the Bluetooth sensor is the better choice when you need higher resolution data or the LCD display. On the other hand it can't measure below freezing.
