Verdict
The clearest difference is ads: Prime Factorization at none against ぶしゅプッシュ's shown. Prime Factorization also leads on iOS requirement (7.1 vs 14.0). ぶしゅプッシュ's advantage is update cadence (every 2 weeks vs every 6 weeks). On price, in-app purchases and device support there is nothing between them.
