head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Optimization · Practiced Mastery
Tests class counter knowledge and objective control with lighter economy than classic RTS.

Optimization · Practiced Mastery
Tolkien-licensed RTS with freeform base building and large-scale faction warfare.
Command & Conquer 4: Tiberian Twilight leans Optimization (Practiced Mastery); The Lord of the Rings: The Battle for Middle-earth II 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.
Command & Conquer 4: Tiberian Twilight
Unit micro and crawler repositioning under pressure
The Lord of the Rings: The Battle for Middle-earth II
Moderate APM demands, forgiving unit control
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Command & Conquer 4: Tiberian Twilight
Class picks and feints against humans reward prediction
The Lord of the Rings: The Battle for Middle-earth II
Human opponents in skirmish reward prediction
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Command & Conquer 4: Tiberian Twilight
Little hidden beyond fog of war
The Lord of the Rings: The Battle for Middle-earth II
Mostly open information, light randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Command & Conquer 4: Tiberian Twilight
Class counters, population caps and objective control are studyable
The Lord of the Rings: The Battle for Middle-earth II
Economy, base layout, and faction counters drive wins
