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 G6
Superseded. Choose it only if a pump or clinic you depend on still requires it — otherwise the G7 is more accurate and warms up far faster.
