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

Cops-and-robbers spin on Battlefield built around heists, chases, and urban shootouts.

Execution · Competitive PvP
A hero battle royale where teamwork and aim against human opponents decides fights.

My Hero Ultra Rumble
