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
A turn-based tactics game testing positioning and squad management under RNG.

Optimization · Pure Optimization
Base-building strategy game about optimizing upgrade economy and raid compositions.

Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Arma Tactics
Turn-based - no twitch demands
Clash of Clans
Troop drop placement is forgiving
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Arma Tactics
Enemy AI scripted; some randomized objectives but no adaptive mind
Clash of Clans
Base layouts anticipate human attackers' habits
Arma Tactics leans a little harder on variance, though the gap is small.
Arma Tactics
Hit chance and randomized missions add real randomness
Clash of Clans
Matchmaking and unseen traps add uncertainty
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Arma Tactics
Positioning, cover and weapon use are the core tactics
Clash of Clans
Army comps, upgrade paths, and attack routing
