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

Execution · Competitive PvP
Timing-based basketball execution layered over playbook knowledge and opponent prediction.

Execution · Competitive PvP
The peak-era Konami football game prized for weighty, skill-driven match play.
NBA 2K9 leans Execution (Competitive PvP); Pro Evolution Soccer 6 leans Execution (Competitive PvP).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
NBA 2K9
Shot timing and stick handles set the ceiling
Pro Evolution Soccer 6
First touch, through balls, and dribbles demand precise control
Pro Evolution Soccer 6 leans a little harder on reads, though the gap is small.
NBA 2K9
Online defenders bait passes and adapt to your sets
Pro Evolution Soccer 6
Versus matches are constant feint and positioning prediction
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
NBA 2K9
Shot RNG and bounces add bounded noise
Pro Evolution Soccer 6
Deflections and keeper spills add light randomness
NBA 2K9 leans a little harder on optimization, though the gap is small.
NBA 2K9
Playbooks, matchups and roster management are learnable systems
Pro Evolution Soccer 6
Formations and player roles are studyable
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.
