One thing to consider is everything else that the watch does that the computer will not.
Have the same setup except for the speed sensor. I find the OHR sensor on the VivoActive HR lags too much for bicycle use so I too use a chest strap. I also use a handlebar mount except when the temperature drops below 5C because battery performance drops fast and the watch shuts down. Not everything pairs up flawlessly though. Sometimes my cadence sensor will refuse to pair by itself and have to manually pair it through the watch.
