Verdict
The clearest difference is ads: Infinite Ruler at none against Super Ruler's shown. Infinite Ruler also leads on update cadence (every 7 months vs every 109 months). Super Ruler's advantage is device support (3 vs 1) and iOS requirement (11.0 vs 18.2). On price and in-app purchases there is nothing between them.
