Key parameters which make a heart rate monitor accurate are:
1. The analog to digital conversion rate should be at least 16 bit
2. The number of ECG channels should be 3 ECG channels and more
3. A Mason-Likar electrode placement
4. A trained person who controls the heart rate measurement
5. A software which can handle with noisy ECG signals
6. Further technologies which are available to handle noisy ECG signals
From the devices listed in this tables:

a Cyton board with 3 ECG channels has the best requirements to be the most accurate heart rate monitor for all kinds of activities, but not the «gold standard in research» Polar H10 as it was defined by sports scientists and Rob ter Horst. Countless accuracy tests where done where heart rate monitors are tested and compared to find the most accurate one. But nobody ever has optimized the key parameters to find the most accurate heart rate monitor for all kind of activities which can be built using this knowledge.
