Which should you buy?
The Osmo Action 4 is the clear pick on raw spec strength, leading by 60.0 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.
The GO 3S doesn't pull ahead on any single popular-comparison spec — its strengths sit in the spec table groups rather than the headline advantages.

Both ship with comparable horizon lock, so those specs don't separate the two — focus on the differences below.
