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 ONE+
Dexcom’s value sensor, and the cheapest route to alarms we have found. Worth comparing on yearly cost rather than sensor price, because ten-day wear closes most of the gap to the fifteen-day Abbott sensors.
