Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Execution · Competitive PvP
Play-calling mind games against a human layered over stick execution and roster planning.

Execution · Competitive PvP
Supercell's snappy top-down team brawler built around three-minute objective fights.
All-Pro Football 2K8 leans Execution (Competitive PvP); Brawl Stars 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.
All-Pro Football 2K8
Stick skills on passes, jukes and tackles decide individual plays
Brawl Stars
Aim, dodging, and ability timing in real time
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
All-Pro Football 2K8
Play-calling against a human is a genuine prediction duel
Brawl Stars
Human teams rotate, bait supers, and adapt
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
All-Pro Football 2K8
Catches, fumbles and matchup rolls add per-play noise
Brawl Stars
Bush ambushes and power-cube spawns hide information
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.

Roster construction and playbook knowledge set the floor
Brawl Stars
Brawler matchups and map strategy are learnable
