Which should you buy?
The N1S Ultra 4K edges ahead on the Mars Score (84.6 vs 87.6), but the 3.0-point gap is small enough that the right pick comes down to which spec advantages matter to you.
The TK860i 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 N1S Ultra 4K if you care most about brightness and light source. Its strongest claims are brightness, light source.
Both ship with comparable resolution, short-throw, 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.
