Latest and greatest activity tracker

MoonOverMyHammies7

I have a Polar activity tracker with the band that goes around you and the wrist watch. I bought it several years ago. I know there is a lot of new things out there and I am just wondering what works the best. I have seen some that also help track sleep and other things also. What do you think is the best one to buy?

There is no 'best'. It all depends what you want.
Issues to consider are:
Water proof or not
Sleep tracker wanted?
Wrist/ on show or hidden
Activity or exercise or both
What type of exercise
Budget
Wanted more for accuracy or motivation.
I'm sure there is more.
