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

Execution · Practiced Mastery
A casual rail shooter testing light aim and upgrade-grind management.

Optimization · Practiced Mastery
Wasteland open-worlder upgrading one car to conquer scripted scrap territories.
Angry Birds Transformers leans Execution (Practiced Mastery); Mad Max leans Optimization (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Angry Birds Transformers
Tap-targeting towers on rails needs modest accuracy
Mad Max
Car combat and counter-brawling timing
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Angry Birds Transformers
Pig defences are placed by script, not thought
Mad Max
War boys follow fixed AI
Angry Birds Transformers leans a little harder on variance, though the gap is small.
Angry Birds Transformers
Level layouts shuffle lightly between runs
Mad Max
Open world is static once scouted
Mad Max leans a little harder on optimization, though the gap is small.
Angry Birds Transformers
Character upgrades and energy economy gate progress
Mad Max
Magnum Opus upgrades and stronghold routing
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.
