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

Optimization · Practiced Mastery
An MMO where grinding out solvable gear-enhancement systems dominates over its action combat.

Optimization · Practiced Mastery
Planning a raid in advance, then executing it where one mistake kills.
Black Desert leans Optimization (Practiced Mastery); Tom Clancy's Rainbow Six leans Optimization (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Black Desert
combo-based combat needs real precision
Tom Clancy's Rainbow Six
One bullet kills, so entries demand clean aim
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Black Desert
PvP siege battles reward reading opponents
Tom Clancy's Rainbow Six
Multiplayer raids add human counterplay
Black Desert leans a little harder on variance, though the gap is small.
Black Desert
gear enhancement is heavily randomized
Tom Clancy's Rainbow Six
Terrorist placements are unknown until doors open
Black Desert leans a little harder on optimization, though the gap is small.
Black Desert
grinding routes and builds are solvable
Tom Clancy's Rainbow Six
The pre-mission planning phase is the real game
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.
