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