The real decision
Fitbit Charge 6 and Garmin Venu 3 are not close substitutes. They are two different buying stages.
Fitbit is the low-risk first step. It tells you whether sleep tracking is useful enough to change your behavior. Garmin is the serious upgrade. It gives you a broader recovery dashboard, better workout context, and a watch you can use all day without treating sleep data as a side feature.
The mistake is buying Fitbit and expecting Garmin-level recovery coaching, or buying Garmin before you know you will wear a tracker every night.

Buy Garmin Venu 3 if

Price discipline
Fitbit is the right buy when the question is, “Will I use sleep tracking?” Garmin is the right buy when the question is, “Which recovery platform should I use for the next few years?”
Do not over-upgrade too early. Buy Fitbit if this is an experiment. Buy Garmin if the experiment is already over and you know recovery data will guide sleep, workouts, and rest.
