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 · Pure Mechanics
A relentless wave-clearing shooter that tests sustained aim and movement against massive scripted enemy crowds.

Execution · Pure Mechanics
Tests split-attention execution - typing accurately while dodging scripted bullet hell.
Painkiller (2004) leans Execution (Pure Mechanics); The Textorcist: The Story of Ray Bibbia leans Execution (Pure Mechanics).
The Textorcist: The Story of Ray Bibbia leans a little harder on execution, though the gap is small.
Painkiller (2004)
Constant crowd-control movement against overwhelming enemy counts demands fast aim
The Textorcist: The Story of Ray Bibbia
Typing exorcisms while dodging bullets is a pure split-brain test
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Painkiller (2004)
All enemies are scripted waves with fixed attack patterns
The Textorcist: The Story of Ray Bibbia
Boss patterns are scripted, never adaptive
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Painkiller (2004)
Enemy counts and placements are fixed with minimal unknown elements
The Textorcist: The Story of Ray Bibbia
Patterns are fixed once learned
Painkiller (2004) leans a little harder on optimization, though the gap is small.
Painkiller (2004)
Tarot card selection and level routing provide a thin solvable layer
The Textorcist: The Story of Ray Bibbia
Memorising bullet patterns and prayer text aids consistency
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.
