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

Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Robocraft
Aiming and piloting matter but vehicles are sluggish
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.
Robocraft
Human PvP battles reward outflanking live opponents
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.
Robocraft
Matchmaking and map spawns add mild noise
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.
Robocraft
Block-by-block build crafting and meta loadouts dominate outcomes
The Lord of the Rings: The Battle for Middle-earth II
Economy, base layout, and faction counters drive wins
