Which should you buy?
The UHZ65UST 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 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 UHZ65UST if you care most about brightness / light source. Its strongest claims are brightness, light source, short-throw.
Both ship with comparable resolution, 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.
