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

Execution · Practiced Mastery
A top-down single-touch shooter testing dodging reflexes through Doom-themed runs.

Execution · Twitch Chaos
Kart racing execution moderated by item randomness and learnable track routes.
Mighty Doom leans Execution (Practiced Mastery); Sonic & All-Stars Racing Transformed leans Execution (Twitch Chaos).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Mighty Doom
Single-touch dodging and aiming under fire demands reflexes
Sonic & All-Stars Racing Transformed
Drift timing and transforming vehicle control reward practice
Sonic & All-Stars Racing Transformed leans a little harder on reads, though the gap is small.
Mighty Doom
Enemies and bosses scripted, not adaptive
Sonic & All-Stars Racing Transformed
Human racers add light positional mind games
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Mighty Doom
Randomized loot and level layouts vary runs
Sonic & All-Stars Racing Transformed
Item rolls regularly upend race positions
Mighty Doom leans a little harder on optimization, though the gap is small.
Mighty Doom
Leveling, gear and weapon upgrades drive progression
Sonic & All-Stars Racing Transformed
Track shortcuts and drift-boost routes are learnable
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.
