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
Stacking wobbly bricks quickly while sabotage spells fly between players.

Execution · Practiced Mastery
A twin-stick action shooter testing aim and crowd control against scripted hordes.
Tricky Towers leans Execution (Pure Mechanics); Warhammer 40,000: Kill Team leans Execution (Practiced Mastery).
Tricky Towers leans a little harder on execution, though the gap is small.
Tricky Towers
Placing physics bricks fast under pressure is the core test
Warhammer 40,000: Kill Team
Twin-stick aiming and dodging waves is the action core
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Tricky Towers
Timing spells against specific human rivals adds light prediction
Warhammer 40,000: Kill Team
Enemy hordes are scripted, not adapting minds
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Tricky Towers
Brick sequence and wobble physics inject chaos
Warhammer 40,000: Kill Team
Enemy spawns and drops add bounded randomness
Warhammer 40,000: Kill Team leans a little harder on optimization, though the gap is small.
Tricky Towers
Stable stacking shapes are learnable patterns
Warhammer 40,000: Kill Team
Class abilities and upgrade paths reward planning
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.
