Verdict
The clearest difference is in-app purchases: OUTBREAK SURVIVOR at none against SphereKnight's 1. OUTBREAK SURVIVOR also leads on update cadence (every 2 days vs every 4 months). SphereKnight's advantage is iOS requirement (8.0 vs 17.0). On price, ads and device support there is nothing between them.
