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

Execution · Pure Mechanics
Classic Tetris execution under audiovisual flow, speed still decides everything.

Execution · Pure Mechanics
A minimalist vector rhythm game that generates obstacle courses from any music CD.
Tetris Effect leans Execution (Pure Mechanics); Vib-Ribbon leans Execution (Pure Mechanics).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Tetris Effect
Piece placement under speed and Zone timing is the whole test
Vib-Ribbon
Precise button timing to obstacle patterns is everything
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Tetris Effect
Solo experience with no opponent to model
Vib-Ribbon
No opponent, just the track
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Tetris Effect
Randomised bag is bounded and quickly mappable
Vib-Ribbon
Tracks generated from your own music CDs
Tetris Effect leans a little harder on optimization, though the gap is small.
Tetris Effect
Stacking theory and Zone usage have known optimal lines
Vib-Ribbon
Pattern-to-button mapping is learned, then perfected
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.
