Verdict
The clearest difference is in-app purchases: Block Harmonics at none against Illusion Corridor's 1. Block Harmonics also leads on device support (3 vs 1). Illusion Corridor's advantage is ads (none vs shown) and update cadence (every 2 days vs every 8 days). On price and iOS requirement there is nothing between them.
