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 · Practiced Mastery
Fast aim-and-movement arenas layered over roguelike perk-stacking decisions.

Execution · Practiced Mastery
A bullet-hell roguelike where dodging fixed patterns is the core skill.
Crab Champions leans Execution (Practiced Mastery); Enter the Gungeon leans Execution (Practiced Mastery).
Enter the Gungeon leans a little harder on execution, though the gap is small.
Crab Champions
Aimbot plus perfect movement trivialises the fast arena gunplay
Enter the Gungeon
Bullet-hell dodge-rolling and precise aim define survival.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Crab Champions
Enemies swarm on fixed behaviours, never modelling you
Enter the Gungeon
Bosses use fixed bullet patterns; no adaptation.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Crab Champions
Random loot and perk offerings shape every run's power curve
Enter the Gungeon
Gun and item drops heavily randomized.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Crab Champions
Stacking synergistic perk builds is the run-winning layer
Enter the Gungeon
Synergy hunting and shop routing shape strong runs.
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.
