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
An arcade-style international soccer simulation.

Execution · Practiced Mastery
A modern-war reboot following Tier 1 operators in Afghanistan.
Iss3 leans Execution (Practiced Mastery); Medal of Honor (2010) leans Execution (Practiced Mastery).
Iss3 leans a little harder on execution, though the gap is small.
Iss3
passing and shooting precision
Medal of Honor (2010)
Modern gunplay in campaign and multiplayer
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Iss3
human opponents allow light prediction
Medal of Honor (2010)
Competitive MP adds human prediction
Iss3 leans a little harder on variance, though the gap is small.
Iss3
match physics randomness
Medal of Honor (2010)
Scripted campaign, modest MP randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Iss3
team tactics and formation strategy
Medal of Honor (2010)
Loadouts and map control are learnable
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.
