Verdict
The clearest difference is in-app purchases: Rule 20 at none against Focus/Rest's 1. Rule 20 also leads on update cadence (every 2 days vs every 5 days) and iOS requirement (15.1 vs 17.6). Focus/Rest's advantage is ads (none vs shown). On price and device support there is nothing between them.
