head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Optimization · Practiced Mastery
A cinematic WWII console shooter famous for its D-Day opening.

Optimization · Practiced Mastery
Planning stealth routes and psychic-power use through scripted guard patrols.
Medal of Honor: Frontline leans Optimization (Practiced Mastery); Second Sight leans Optimization (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Medal of Honor: Frontline
Console gunplay through cinematic set-pieces
Second Sight
Aiming and psychic-power juggling under fire need moderate hands
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Medal of Honor: Frontline
Scripted soldiers never adapt
Second Sight
Guard AI runs predictable patrol scripts
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Medal of Honor: Frontline
Set-piece surprises fade after one run
Second Sight
Patrol routes are unknown only on first pass
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Medal of Honor: Frontline
Memorising spawns and routes trivialises missions
Second Sight
Planning stealth routes and power usage solves each level
