Fitness trackers: recommendations on your favorite?

I'm looking to get a fitness tracker to help drive accountability in me to get my health back in shape. Long hours of coding and a social lifestyle that revolves around drinking seems to have done enough damage. Ideally looking for a waterproof one so that I can use it to track my swims when I switch up my activities. Any favorites that you love? As for activities - I like lifting weights in the gym, occasionally run and swim. Not too much biking currently but I might squeeze that in a couple times a week as well. Garmin vivoactive 3 and motiv look neat. Anything else you love and would recommend for the activities above? TIA!
