Anker - Nebula Cosmos Laser 4K vs XGIMI - Horizon Ultra

These two are nearly even on the Mars Score (69.5 vs 68.7). The decision is not about overall quality — both clear the bar — it is about which specific trade-offs fit your use.

Pick the Nebula Cosmos Laser 4K if you care most about brightness. The biggest gaps in its favor are brightness. The single most decisive one: Brightness — 4.35% more. 2400 lm vs 2300 lm.

The Horizon Ultra similarly does not carry a headline advantage on the popular specs — look at the full table for category-specific deltas.

Both ship with comparable resolution, light source, short-throw, so those specs do not separate the two — focus on the differences below.

Bottom line: there is no wrong answer here — match the spec advantages to how you actually use the product. The Mars Score parity says both are well-rounded; the differences are about trade-offs, not quality.
