Again, I think the central question in any PWR:HR analysis is how much accuracy do you need?
I often see folks compare HR between athletes and then power between athletes and say see how much more reliable power is... Paraphrased of course. But yea.
On the edge numbers I see smoother lines for HR than power. I have not looked into sampling rates, but just about any Strava TT for a leader that post both power and HR - the HR plot is smoother.
