head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Execution · Practiced Mastery
A blistering DS Sonic built around the boost gauge, introducing Blaze the Cat.

Execution · Practiced Mastery
A 3D platformer where precise movement and camera mastery unlock its many challenges.
Sonic Rush leans Execution (Practiced Mastery); Super Mario 64 DS leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Sonic Rush
Boost management and trick timing at high speed
Super Mario 64 DS
precise 3D platforming and camera control
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Sonic Rush
Scripted bosses only
Super Mario 64 DS
scripted enemies, no adaptation
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Sonic Rush
Dual-screen layouts surprise on first runs
Super Mario 64 DS
minimal randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Sonic Rush
Rank grinding turns levels into solved boost routes
Super Mario 64 DS
star routes and speedrun tech solvable
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.
