Worth it to upgrade from Apple Watch/HR strap if I don't do endurance work?

I'm currently using an Apple Watch and Polar HR strap to track my HR and burned calories (I know this is wildly inaccurate), to gauge progress in my conditioning. I largely use it on a Rogue echo bike, pushing a sled, farmers carries and hill sprints.

I am not a runner and don't plan to do any serious running any time soon. I am unlikely to use the GPS features. Those who have made the switch, is it worth it to upgrade to a Garmin watch (any of the countless models) for more HR and recovery based metrics, or do I just have new-gear-itis?
