Which should you buy?
The Watch GT 6 is the clear pick on raw spec strength, leading by 10.5 points on the Mars Score. The margin is wide enough that the underdog only makes sense if its individual strengths line up with what you specifically need.
Pick the vívoactive 5 if you carry the device everywhere and weight or thickness has been the deciding factor before. The biggest gaps in its favor are weight.
Pick the Watch GT 6 if your top frustration with your current device is running out of charge before the day ends — endurance is the lead spec here. Its strongest claims are peak brightness, battery life, display size, among others.
Both ship with comparable cellular, spo2, water resistance, so those specs don't separate the two — focus on the differences below.
Bottom line: the Watch GT 6 is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
