head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is variance, and it is a single point.

Optimization · Pure Optimization
Mobile production-chain and layout optimisation paced by timers.
Dragon Quest VIII: Journey of the Cursed King leans Optimization (Pure Optimization); SimCity BuildIt 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.
Dragon Quest VIII: Journey of the Cursed King

SimCity BuildIt
Tapping menus has no skill floor
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Dragon Quest VIII: Journey of the Cursed King

Dragon Quest VIII: Journey of the Cursed King
Battle RNG, drops, and casino luck
SimCity BuildIt
Market prices and material drops add mild randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Dragon Quest VIII: Journey of the Cursed King
Skill points, alchemy, and tension are optimizable
SimCity BuildIt
Production chains, layout and currency timing are the whole game
