Which should you buy?
The UHZ65UST edges ahead on the Mars Score (80.1 vs 87.6), but the 7.5-point gap is small enough that the right pick comes down to which spec advantages matter to you.
The PX3-Pro 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. Its strongest claims are brightness.
Both ship with comparable resolution, light source, short-throw, so those specs do not separate the two — focus on the differences below.
