Fitbit Sense 2 & Garmin vívosmart 5 share many similarities, but there are also important differences, such as quality, performance, features, design, and connectivity. If you want the best one between them, I Would recommend the Fitbit Sense 2 rather than the Garmin vívosmart 5.

Why Do I Recommend The Fitbit Sense 2?
- The Fitbit Sense 2 features an ECG sensor for detecting signs of irregular heart rhythms and supporting proactive cardiac monitoring, whereas the Garmin Vivosmart 5 does not include ECG functionality.
- Fitbit Sense 2 includes an EDA stress sensor to identify real-time physiological stress responses and support guided stress-management routines, while the Garmin Vivosmart 5 uses heart-rate-based stress estimates without an EDA sensor.
- It comes with a built-in microphone and speaker to enable Bluetooth phone calls directly from the wrist for hands-free communication, whereas the Garmin vivosmart 5 lacks microphone and speaker hardware.
- The Fitbit Sense 2 supports on-device voice assistant integration for setting reminders, controlling smart devices, and quick information access, while the Garmin vivosmart 5 does not support any voice assistant features.
- Fitbit Sense 2 has a larger AMOLED touchscreen display for easier reading of notifications, health metrics, and workout data at a glance, compared to the Garmin vivosmart 5’s smaller, band-style display.
- It includes skin temperature variation tracking during sleep to help identify changes related to illness, recovery, or environment, whereas the Garmin vivosmart 5 does not track skin temperature.
- The Fitbit Sense 2 supports on-watch apps and a broader smartwatch-style interface for managing health data, settings, and smart features directly on the device, while the Garmin vivosmart 5 focuses on a more limited fitness-band interface.
- Fitbit Sense 2 features a smartwatch form factor with a larger battery capacity and more onboard processing for advanced health analytics and real-time feedback, whereas the Garmin vivosmart 5 prioritizes simplicity with fewer advanced health sensors.
Maybe the Garmin vívosmart 5 price can make you comfortable because it’s a little bit cheaper than the Fitbit Sense 2. But you have to compromise all the above-mentioned features. Now the Decision is Yours. I hope it was helpful to choose the right one.
