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Superseded.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.
FreeStyle Libre 3 Plus
The most convenient of the Abbott sensors, and the longest wear time you can currently buy. If you qualify for NHS funding, get it that way — the private price is roughly £140 a month.
