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 · Pure Mechanics
Tests rhythm execution against fixed EDM note charts.

Execution · Pure Mechanics
Sequel rhythm game with harder setlists and refined plastic-guitar technique.
Avicii Invector leans Execution (Pure Mechanics); Guitar Hero II leans Execution (Pure Mechanics).
Guitar Hero II leans a little harder on execution, though the gap is small.
Avicii Invector
Note-perfect timing through track charts is the whole test
Guitar Hero II
Harder charts, hammer-ons, and three-note chords
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Avicii Invector
Charts never adapt - pure performance
Guitar Hero II
Static note highways
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Avicii Invector
Every chart is fixed and rehearsable
Guitar Hero II
Fully deterministic charts
Avicii Invector leans a little harder on optimization, though the gap is small.
Avicii Invector
Score routes and multiplier management add a thin layer
Guitar Hero II
Star power pathing for leaderboard play
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.
