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.

Execution · Competitive PvP
Free-to-play hero shooter where loadout cards customize champions in objective team fights.

Execution · Pure Mechanics
A simulation tennis game built around precise shot-timing rallies.
Paladins leans Execution (Competitive PvP); Top Spin 4 leans Execution (Pure Mechanics).
Top Spin 4 leans a little harder on execution, though the gap is small.
Paladins
Hitscan aim and ability timing in firefights
Top Spin 4
Shot timing meter decides every rally
Paladins leans a little harder on reads, though the gap is small.
Paladins
Human teams flank, bait ults, and adapt
Top Spin 4
Human PvP rewards anticipating placement habits
Paladins leans a little harder on variance, though the gap is small.
Paladins
Card draft order adds mild run variance
Top Spin 4
Almost no randomness in ball physics
Paladins leans a little harder on optimization, though the gap is small.
Paladins
Loadout card builds and item counter-buying
Top Spin 4
Player builds and court tactics are learnable
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.
