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
Open-world driving that tests car control with a tuning layer underneath.

Execution · Practiced Mastery
Precision car control of vintage machinery refined through setup and line study.
Forza Horizon leans Execution (Practiced Mastery); GT Legends leans Execution (Practiced Mastery).
GT Legends leans a little harder on execution, though the gap is small.
Forza Horizon
Driving skill with assists off carries every event
GT Legends
Historic cars without aids demand precise car control every corner
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Forza Horizon
AI drivatars follow patterns; casual online adds little
GT Legends
Racecraft versus humans exists but pace dominates
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Forza Horizon
The open world is fixed and fully discoverable
GT Legends
Conditions are known before the green flag
GT Legends leans a little harder on optimization, though the gap is small.
Forza Horizon
Car tuning and racing lines reward systematic study
GT Legends
Setup tuning and line study are where lap time lives
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.
