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
High-tempo brawler execution against fixed crowd choreography.

Execution · Practiced Mastery
Sonic alternates breakneck daytime boost stages with brawling night levels as the Werehog.
Midnight Fight Express leans Execution (Pure Mechanics); Sonic Unleashed leans Execution (Practiced Mastery).
Midnight Fight Express leans a little harder on execution, though the gap is small.
Midnight Fight Express
Crowd-control timing, counters and weapon juggling carry levels
Sonic Unleashed
Daytime boost stages demand reaction-speed precision
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Midnight Fight Express
Thugs attack on scripted cues
Sonic Unleashed
Scripted enemies in both forms
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Midnight Fight Express
Fixed level setups every attempt
Sonic Unleashed
First-run stage hazards arrive fast and unseen
Sonic Unleashed leans a little harder on optimization, though the gap is small.
Midnight Fight Express
Skill unlocks and route knowledge polish scores
Sonic Unleashed
S-rank routes and Werehog combat upgrades are solvable
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.
