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.

Optimization · Practiced Mastery
Solving block-tower routes quickly enough to outrun the timer.

Optimization · Practiced Mastery
Spice economy management and build-order knowledge with modest micro demands.
Catherine: Full Body leans Optimization (Practiced Mastery); Dune 2000 leans Optimization (Practiced Mastery).
Catherine: Full Body leans a little harder on execution, though the gap is small.
Catherine: Full Body
Climbing fast under a rising floor demands quick precise inputs
Dune 2000
Unit micro and build speed matter at competitive pace
Dune 2000 leans a little harder on reads, though the gap is small.
Catherine: Full Body
Versus modes against humans add a thin prediction layer
Dune 2000
Human skirmishes add some build-order mind games
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Catherine: Full Body
Block layouts are fixed; little randomness once learned
Dune 2000
Fog of war hides enemy composition until scouted
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Catherine: Full Body
Block-pushing techniques and route knowledge are the real ceiling
Dune 2000
Spice economy and build orders decide most games
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.
