head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.

Execution · Practiced Mastery
Kart racer whose boost-chaining drift system gives it a real execution ceiling.

Execution · Pure Mechanics
The first online Mario Kart, infamous for the execution-heavy snaking technique dominating play.
Crash Team Racing leans Execution (Practiced Mastery); Mario Kart DS leans Execution (Pure Mechanics).
Mario Kart DS leans a little harder on execution, though the gap is small.
Crash Team Racing
Boost-chaining and drift timing separate skill tiers
Mario Kart DS
Snaking demands relentless precise drift inputs
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Crash Team Racing
Human races involve item baiting and blocking
Mario Kart DS
Online opponents punish predictable lines
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Crash Team Racing
Item box rolls swing positions
Mario Kart DS
Item RNG decides tight finishes
Crash Team Racing leans a little harder on optimization, though the gap is small.
Crash Team Racing
Shortcut routes and reserve-boost technique
Mario Kart DS
Kart stats, lines, and snaking routes
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.
