Neither is meaningfully harder - they pose close to the same test. The widest gap is variance, 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.
Everlasting Summer
No opponent - characters follow fixed branching scripts
Muv-Luv

Everlasting Summer leans a little harder on variance, though the gap is small.

Muv-Luv
Minimal hidden information in the first entry
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.

Mapping choice branches to endings is trivially solvable
Muv-Luv
Completing Muv-Luv and Unlimited to unlock Alternative is a light routing puzzle
