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

Optimization · Pure Optimization
A live-service Fallout where perk-card builds and CAMP crafting drive progression.

Optimization · Pure Optimization
A lore-faithful MMORPG where trait tree builds and fellowship coordination decide raid performance.
Fallout 76 leans Optimization (Pure Optimization); The Lord of the Rings Online leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Fallout 76
Shooter inputs in live combat
The Lord of the Rings Online
Raid content has limited twitch demand versus action MMOs
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Fallout 76
PvP exists but most play is PvE
The Lord of the Rings Online
Mostly PvMP monster play; rarely the main loop
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Fallout 76
Legendary and event loot rolls
The Lord of the Rings Online
Loot RNG and deed completion add minor hidden layers
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Fallout 76
Perk cards, CAMP, build crafting key
The Lord of the Rings Online
