If you're torn between the Amazfit T-Rex and the Fitbit Versa 2, it's not hard to see why. Both of these fitness smartwatches are packed with useful features. That being said, they cater to slightly different crowds. Those who want superior fitness tracking along with some other bonus perks will likely lean toward the Fitbit Versa 2. If you're a rugged outdoorsman who needs a tough watch that can keep up with you, then you might find yourself eyeing the Amazfit T-Rex. The major difference is that the Fitbit Versa 2 does not have built-in GPS. Other than that one flaw, it is the better choice for dedicated health and fitness enthusiasts.

Not surprisingly, the second edition of the Versa maintains its unique squircle design that has become so recognizable over the years. It has a beautiful AMOLED display that's easy to navigate. The modestly-sized 40 mm aluminum case and five different color options. You can easily swap out the band whenever you feel like changing things up. You'll also enjoy 5 ATM water resistance and 5 days of battery life with typical use.

You'll need your phone to use connected GPS, though.

There are other features outside of fitness tracking to look forward to as well. The Versa 2 has Amazon Alexa built-in, which allows you to talk to your watch. Whether you want to know what the weather is like outside or you need to set a reminder to exercise, this is a nice addition to the watch. Keep in mind that there is no speaker present, so you'll need to look at your watch for any responses from Amazon Alexa. You also have smartphone notifications, music storage for 300 songs, decent app support, and mobile payments with Fitbit Pay.
