Insta360 - Ace Pro 2 vs Insta360 - ONE RS (Twin Edition)

The Ace Pro 2 is the clear pick on raw spec strength, leading by 36.4 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 Ace Pro 2 if you care most about waterproof depth and max 4k fps. The biggest gaps in its favor are waterproof depth, max 4k fps, max video.

The ONE RS (Twin Edition) similarly doesn't carry a headline advantage on the popular specs — look at the full table for category-specific deltas.

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