Score: 80/100
Fitbit Inspire 3
Score: 77/100Rankings

The Garmin Forerunner 55 is an entry-level GPS running smartwatch offering up to two weeks of battery life and a lightweight 37 g design. It lacks advanced sensors such as SpO₂ and music playback, focusing on core running features. Best for beginner and recreational runners who prioritize simplicity and endurance.

The Fitbit Inspire 3 is a slim, lightweight fitness tracker that excels with a 120-hour battery and built-in GPS. Its trade-off is a tiny screen and lack of advanced smartwatch features. Best for users who want basic health monitoring and swimming capability without a bulky device.
