I don’t know. It partially depends on your needs.
ConsumersAdvocate.org has an article comparing and contrasting some of the available fitness trackers:
HOW WE FOUND THE BEST FITNESS TRACKERFEATURES
We checked for fitness trackers with diverse features that users could choose to best match their lifestyle and goals. This includes multiple health and activity monitoring options.
Many fitness trackers sync with smartphones or Bluetooth to receive calls, get message notifications, and send data to their corresponding fitness apps. We looked at trackers that were easy to connect.
Regular fitness trackers can range from $50 to $200, while hybrid smartwatches can cost over $400. We compared prices to special features to make sure consumers get the most out of their investment.
Fitness trackers should be durable, lightweight, and comfortable. We interviewed customers and read dozens of reviews and testimonies for thorough feedback on each product.
