Verdict
The clearest difference is in-app purchases: Puchi Bubble at none against Prime Numberist's 3. Puchi Bubble also leads on ads (none vs shown) and update cadence (every 2 weeks vs every 6 weeks). Prime Numberist's advantage is iOS requirement (12.0 vs 15.0). On price and device support there is nothing between them.
