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 combo-driven action RPG where managing the Break Soul economy through scripted enemy encounters is the central test.

Execution · Practiced Mastery
Co-op-focused action sequel hurling Titus against Tyranid swarms with parry-heavy melee combat.
Tales of Berseria leans Execution (Practiced Mastery); Warhammer 40,000: Space Marine 2 leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Tales of Berseria
Break Soul chains and timing under Break Soul economy demand execution
Warhammer 40,000: Space Marine 2
Parry, dodge and gun-strike timing against swarms
Warhammer 40,000: Space Marine 2 leans a little harder on reads, though the gap is small.
Tales of Berseria
All enemies use fixed attack scripts; no adaptive component
Warhammer 40,000: Space Marine 2
PvP Eternal War adds some human prediction
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Tales of Berseria
Random drops matter for gear progression but rarely alter fights
Warhammer 40,000: Space Marine 2
Tyranid swarm spawns vary run to run
Tales of Berseria leans a little harder on optimization, though the gap is small.
Tales of Berseria
Soul Gauge and Break Soul management form the optimisation layer
Warhammer 40,000: Space Marine 2
Class builds and perk loadouts 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.
