Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Battlefield Hardline
Cops-versus-criminals humans adapt heist tactics
Pro Evolution Soccer 2009

Battlefield Hardline leans a little harder on variance, though the gap is small.
Battlefield Hardline
Spawns and loot grabs shuffle engagements
Pro Evolution Soccer 2009
Ricochets and keeper parries add small randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Battlefield Hardline
Gadget loadouts and mode-specific route knowledge
Pro Evolution Soccer 2009
Squad setup and tactical sliders reward preparation
