Accu-Chek SmartGuide
The most genuinely different sensor here: the prediction features target the thing people actually fear, which is going low overnight. The trade-off is going back to calibration, and Roche publishing less about accuracy than its competitors.
Dexcom G7
The sensor to pick if you want alarms, remote following, or pump integration. The gap between its pivotal accuracy figure and the independent one is the widest of any sensor we list, and worth knowing about.
