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.
Medtronic Simplera
The sensor to look at if you use or want a MiniMed 780G pump, because that integration is the reason it exists. As a standalone sensor the seven-day wear and two-hour warm-up make it hard to recommend over the alternatives.
