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

A tennis simulation where timing execution and reading opponent tendencies drive competitive outcomes.

Execution · Competitive PvP
Combined-arms multiplayer shooter famous for map-altering levolution moments and 64-player conquest.

Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
AO Tennis 2
Ball timing and serve placement have clear skill ceilings
Battlefield 4
Gunplay, vehicle mastery, and movement under fire
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
AO Tennis 2
Online human opponents create adaptive rally patterns
Battlefield 4
Human teams adapt to flanks and levolution chokes

Very little luck in outcomes
Battlefield 4
Map-altering events and spawns inject noise
Battlefield 4 leans a little harder on optimization, though the gap is small.
AO Tennis 2
Player builds and tactical shot variety are learnable systems
Battlefield 4
Loadout tuning and objective rotation knowledge
