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.

House Flipper 2 leans Optimization (Pure Optimization); PowerWash Simulator leans Optimization (Pure Optimization).
PowerWash Simulator leans a little harder on execution, though the gap is small.

Aim and sweep nozzle precision
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
