So 170 bpm could be 168-172 with chest strap, 153-187 with Apple Watch, and 136-204 with other wrist sensors . . .
For serious exercise use, seems like there's no substitute for a chest strap.

I would say absolutely. The issue is cost. To the get highest level will require the strap PLUS another device which interfaces with it, typically a Garmin unit.
Will the Apple Watch connect to a heart rate strap?
