head to head
Mario Kart World asks more than Mario Kart 8, and the gap is reads.

Execution · Twitch Chaos
A kart racer where controlled chaos from random items tempers otherwise precise driving skill.

Execution · Twitch Chaos
Kart racing blending drift execution with item RNG and pack positioning.
Mario Kart 8 leans Execution (Twitch Chaos); Mario Kart World leans Execution (Twitch Chaos).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Mario Kart 8
precise drifting and item timing matter
Mario Kart World
Drift charging, rail grinding and shortcut precision reward hands
Mario Kart World leans clearly harder on reads.
Mario Kart 8
minimal, mostly reacting not predicting
Mario Kart World
Human racers bait items and contest lines in knockouts
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Mario Kart 8
item boxes are heavily randomized
Mario Kart World
Item rolls and rubber-banding scramble any single race
Mario Kart 8 leans a little harder on optimization, though the gap is small.
Mario Kart 8
track lines and item strategy solvable
Mario Kart World
Course knowledge, shortcuts and item management converge with study
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.
