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 movie tie-in testing combo timing against scripted duels.

Execution · Competitive PvP
Class-based battlefield brawling where picking counters beats raw skill.
Star Wars: Episode III - Revenge of the Sith leans Execution (Practiced Mastery); The Lord of the Rings: Conquest leans Execution (Competitive PvP).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Star Wars: Episode III - Revenge of the Sith
Lightsaber combos and blocks need modest timing
The Lord of the Rings: Conquest
Class combos and timing carry battlefield skirmishes
The Lord of the Rings: Conquest leans a little harder on reads, though the gap is small.
Star Wars: Episode III - Revenge of the Sith
Versus duel mode adds light human prediction
The Lord of the Rings: Conquest
Multiplayer class counters involve light human prediction
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Star Wars: Episode III - Revenge of the Sith
Encounters are fixed movie-scripted setpieces
The Lord of the Rings: Conquest
Objective maps are fixed and visible
Star Wars: Episode III - Revenge of the Sith leans a little harder on optimization, though the gap is small.
Star Wars: Episode III - Revenge of the Sith
Combo unlocks and boss patterns are quickly mapped
The Lord of the Rings: Conquest
Class-counter knowledge and objective sequencing are shallow
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.
