Mario Kart DSvsTetris 99
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.
Mario Kart DS
Execution · Pure Mechanics
The first online Mario Kart, infamous for the execution-heavy snaking technique dominating play.
Tetris 99
Execution · Pure Mechanics
Battle royale Tetris where raw stacking speed decides who outlasts 98 opponents.
Mario Kart DS leans Execution (Pure Mechanics); Tetris 99 leans Execution (Pure Mechanics).

Execution8 vs 9
Tetris 99 leans a little harder on execution, though the gap is small.
Mario Kart DS
Snaking demands relentless precise drift inputs
Tetris 99
High-speed stacking and finesse define survival

Tetris 99 leans a little harder on reads, though the gap is small.
Mario Kart DS
Online opponents punish predictable lines
Tetris 99
Targeting and badge timing against humans matter mid-match
Variance4 vs 4
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Mario Kart DS
Item RNG decides tight finishes
Tetris 99
Incoming garbage timing and piece sequence add chaos
Optimization5 vs 5
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.

Stacking theory and downstack efficiency are studied skills
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
