I've used Garmins and Apple watches for years now. As an avid road cyclist, I always used some type of Garmin wrist device for heart rate monitoring. As a tech person, I always found the Apple watch to be more on the 'smart watch / techie' side of things - and more aesthetically pleasing. There is no doubt that the Garmin does a better job of actually recording a ride, or transmitting heart rate to your cycling computer, or just about anything activity-based. So I was always swapping my Apple for my Garmin before rides, workouts, etc. I always knew there was a shortcoming with even the Garmin when it came to heart rate accuracy - it just didn't respond quickly enough to sudden changes in heart rate (ie. going up a hill at full throttle, etc) - so I tried a heart rate strap on the chest. The Garmin heart rate strap for the chest is perfectly accurate and responds to changes in heart rate immediately. I have that paired with my cycling computer on my bike...and I no longer swap watches depending on what I'm doing. I've learned to appreciate the Apple Watch for what it is - a device to record activities where heart rate accuracy isn't necessarily 100% important - such as a quick training jog or a quick treadmill workout at the gym, etc. In either event, I've rambled long enough. I'll be first in line for the new Apple Watch 4 - and will sell my Apple Watch 3 shortly after. I might keep my old wrist strap though. :D
