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.

Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
International Superstar Soccer Deluxe
Versus a human, faking runs and reading tackles is central
Paladins

Paladins
