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

Execution · Competitive PvP
WWII team shooter blending aim and squad tactics.

Execution · Competitive PvP
An arena shooter testing aim and predicting opponents who can flank through portals.
Battlefield V leans Execution (Competitive PvP); Splitgate: Arena Reloaded 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.
Battlefield V
Bullet drop and recoil punish sloppy aim
Splitgate: Arena Reloaded
Arena aim plus portal movement sets a high mechanical bar
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Battlefield V
Flanks and squad play reward map sense
Splitgate: Arena Reloaded
Predicting where humans will portal from is constant
Battlefield V leans a little harder on variance, though the gap is small.
Battlefield V
Vehicle spawns and chaos create swings
Splitgate: Arena Reloaded
Spawns and weapon timers add mild uncertainty
Battlefield V leans a little harder on optimization, though the gap is small.
Battlefield V
Class loadouts and fortifications optimize holds
Splitgate: Arena Reloaded
Portal setups and map control patterns are learnable theory
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.
