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.

Optimization · Practiced Mastery
A strategy shooter testing defense placement economy backed by active gunplay.

Optimization · Practiced Mastery
Zelda-flavored musou about juggling battlefield objectives while mowing hordes.
Fortified leans Optimization (Practiced Mastery); Hyrule Warriors 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.
Fortified
Third-person shooting between waves keeps hands busy
Hyrule Warriors
Combo strings and weak-point gauge timing
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Fortified
Martian waves are scripted compositions
Hyrule Warriors
Enemy hordes are mindless and scripted
Fortified leans a little harder on variance, though the gap is small.
Fortified
Wave makeup is known after a single attempt
Hyrule Warriors
Minor drop and mission randomness
Fortified leans a little harder on optimization, though the gap is small.
Fortified
Defense placement and hero loadout economy decide rounds
Hyrule Warriors
Keep management, character builds, and map priorities
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.
