What would everyone say is the best cgm around?
I’m currently on freestyle libre 2 but have recently been having issues on accuracy
 
Depends.
For starters what is your definition of "best"- cheapest, most accurate, easiest to get, supported by your phone, what functionality do you need...?
Then there is just our individual body - some people have no issues with Libre (it's the most common), many people who try a Dexcom say that is less fault prone (but I found it less accurate and had a 50% failure rate).
Finally, it is important to remember that all CGMs are designed to be most accurate at "normal" BG levels and, like finger prick meters, need only be within 15% of the "real" BG. If your levels are in double figures or your finger prick meter you are comparing it with is 15% out in the opposite direction. no CGM will appear accurate when compared with finger pricks.

The Dexcom One+ has the same form factor as the Dexcom G7 - small with a built in Bluetooth transmitter.
The Dexcom One+ does have a calibration function so you can match the readings to your blood sugar meter.
The Dexcom One+ cheaper than the Libre 2Plus on a monthly or quarterly subscription.
The Dexcom One+ can show data on an Apple watch (via an iPhone)
The Dexcom G7 can talk directly to an Apple Watch.
