Here's a comprehensive article about the Fitbit 3 Versa:

The Fitbit 3 Versa and its newer counterpart, the Fitbit 4 Versa, share many similarities in terms of features and functionality. However, one major difference is the inclusion of a button on the left-hand side of the Fitbit 4 Versa. At first glance, this may seem like an exciting upgrade, but upon closer inspection, it's clear that this feature doesn't offer much in the way of significant improvements.

One of the main issues with the Fitbit 4 Versa is its poor activity tracking due to spotty GPS syncing. This can result in inaccurate distance readings and difficulties in estimating distances during lapses in signal strength. In comparison, the Fitbit 3 Versa did not have these same issues, making it a more reliable choice for those who rely on accurate tracking.

In terms of features, both devices offer metrics for blood oxygen levels, sleep tracking, heart rate monitoring, and compatibility with a wide range of exercises such as trail running, snowboarding, and cycling. The tracking features are roughly identical for the Versa 3 and 4, so there isn't much of an upgrade.

The inclusion of the button on the Fitbit 4 Versa may seem like a welcome addition, but in reality, it's more of an aesthetic feature than anything else. Pushing the button twice prompts Amazon's Alexa assistant, while holding it down displays a handful of your daily activity stats. This may be seen as a novelty by some, but for most users, it won't make a significant difference.

In fact, the only discernible hardware difference between the two devices is the inclusion of this button on the left-hand side of the Fitbit 4 Versa. The rest of the physical aspects of the device remain the same as the Fitbit 3 Versa, including its 1.58-inch AMOLED screen and touch controls for navigation.

Alexa and Google Assistant still have complete functionality on both devices, allowing users to access fitness data, trackable activities, and various apps with ease. The Versa 4's design is almost identical to the Versa 3's, making it difficult to recommend the newer model over its predecessor.

For longtime Versa wearers, the inclusion of a button may seem like a reversal of Fitbit's trend of cutting down on physical buttons with each iteration of the series. However, for new users, this feature likely won't make much of an impact.

In conclusion, the Fitbit 4 Versa's additional button is more of an aesthetic feature than anything else, and its poor activity tracking due to spotty GPS syncing makes it a less reliable choice compared to the Fitbit 3 Versa. Unless you're looking for a device with a specific design feature, there isn't much reason to upgrade from the Fitbit 3 Versa to the Fitbit 4 Versa.
