Who Has The Most Accurate Heart Rate Monitor?

On a day to day basis I use a FitBit Charge given me by my wife. I had a stent implant not long ago. There was a heart rehab series covered by my insurance so figured what the heck. It was six weeks and you wore a harness with three electrodes, etc. You could observe your heart rate on a screen up front. The FitBit was quite accurate. I use a Mio Link while riding though because I have not yet figured out how to get Strava to pickup heart rate from my FitBit.
