Between the W5800 and X2-4K, the W5800 comes out ahead in several specs, while the X2-4K wins on brightness and short-throw. Overall, the W5800 scores 73.9 and the X2-4K scores 78.6 on our Mars Score.
Which should you buy?
The X2-4K edges ahead on the Mars Score (73.9 vs 78.6), but the 4.7-point gap is small enough that the right pick comes down to which spec advantages matter to you.
The W5800 doesn't pull ahead on any single popular-comparison spec — its strengths sit in the spec table groups rather than the headline advantages.
Pick the X2-4K if you care most about brightness and short-throw. Its strongest claims are brightness, short-throw.
Both ship with comparable resolution, light source, so those specs don't 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 tells you both are well-rounded; the differences are about trade-offs, not quality.
