Verdict
The clearest difference is in-app purchases: Invader Sisters at none against Red Conquest!'s 1. Invader Sisters also leads on update cadence (every 2 weeks vs every 3 months) and iOS requirement (12.0 vs 16.0). Red Conquest!'s advantage is ads (none vs shown). On price and device support there is nothing between them.
