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

Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Beholder
Tenants follow scripted schedules, not adaptive
Plants vs. Zombies 2: It's About Time
Zombie waves are announced patterns, not minds
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.

Plants vs. Zombies 2: It's About Time
Wave compositions and plant-food drops add per-level randomness
