Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.

Deathmatch Classic leans a little harder on execution, though the gap is small.
Deathmatch Classic
aim and movement decide every fight
Pro Evolution Soccer 6
First touch, through balls, and dribbles demand precise control
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Deathmatch Classic
human opponents predict positioning and timing
Pro Evolution Soccer 6

Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Deathmatch Classic
weapon and spawn randomness
Pro Evolution Soccer 6
Deflections and keeper spills add light randomness
Pro Evolution Soccer 6 leans a little harder on optimization, though the gap is small.
Deathmatch Classic
limited map and weapon-control knowledge
Pro Evolution Soccer 6
