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
Push-forward arena FPS where movement and aim are the whole game.

Execution · Pure Mechanics
A twin-stick arcade shooter framed as a lethal game show of swarming arenas and prizes.
DOOM (2016) leans Execution (Pure Mechanics); Smash TV leans Execution (Pure Mechanics).
Smash TV leans a little harder on execution, though the gap is small.
DOOM (2016)
Aim, movement, glory-kill timing all peak.
Smash TV
Twin-stick aim and dodging through swarming arenas is everything.
DOOM (2016) leans a little harder on reads, though the gap is small.
DOOM (2016)
Demons scripted attack patterns.
Smash TV
Mobs rush mindlessly on scripts.
Smash TV leans a little harder on variance, though the gap is small.
DOOM (2016)
Minimal encounter randomness.
Smash TV
Spawn timing and pickups vary modestly.
DOOM (2016) leans a little harder on optimization, though the gap is small.
DOOM (2016)
Rune and weapon mod picks meaningful.
Smash TV
Room order, powerup priorities, and boss patterns 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.
