Wearable Fitness Trackers

[SPINMAN]

I'm wanting to change to a different wearable Fitness tracker. I have been using fitbit for years and currently using the Sense. Fitbit is now owned by Google. Don't know if that's good or bad. It has lots of sports available to sense. I need it to be able to use in the water for swimming. Mostly swim bike run but some hiking and HITT activities. Fitbit is OK but heart rate very delayed and not the most accurate. Distance seems accurate. What do you think? Anything better than a fitbit?
Thanks
