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
Consistent lap-time precision supported by tuning and racing-line study.

Execution · Practiced Mastery
A realistic motorcycle racing sim about precise lines, braking and bike setup.
Forza Motorsport 7 leans Execution (Practiced Mastery); MotoGP 21 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.
Forza Motorsport 7
Braking points, throttle control and racing lines are everything
MotoGP 21
Braking points, throttle and racing lines demand precision
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Forza Motorsport 7
Online racecraft adds light human positioning play
MotoGP 21
AI scripted; online rivals add light positional prediction
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Forza Motorsport 7
Dynamic weather shifts conditions mid-race
MotoGP 21
Tire wear and weather introduce some chance
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Forza Motorsport 7
Tuning setups and line study reward engineering effort
MotoGP 21
Setup tuning and race strategy underpin lap times
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.
