Which should you buy?
The UM790 Pro edges ahead on the Mars Score (68.6 vs 71.8), but the 3.2-point gap is small enough that the right pick comes down to which spec advantages matter to you.
The NucBox K11 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 UM790 Pro if you care most about tdp and volume. Its strongest claims are tdp, volume.
