Which should you buy?
The Horizon S Max is the clear pick on raw spec strength, leading by 35.1 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 Nebula Mars 3 does not pull ahead on any single popular-comparison spec — its strengths sit in the spec-table groups rather than the headline advantages.
Pick the Horizon S Max if you care most about brightness / resolution. Its strongest claims are brightness, resolution.
Both ship with comparable light source, short-throw, so those specs do not separate the two — focus on the differences below.
Bottom line: the Horizon S Max is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
