Which should you buy?
These two are nearly even on the Mars Score (80.1 vs 78.6). The decision is not about overall quality — both clear the bar — it is about which specific trade-offs fit your use.
Pick the PX3-Pro if you care most about brightness. The biggest gaps in its favor are brightness.
The X2-4K 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.
