Verdict

The call

The clearest difference is ads: Faxbot at none against AO Office's shown. Faxbot also leads on review sentiment (72% vs 39%). AO Office's advantage is update cadence (every 5 weeks vs every 8 months) and monetization model (free with in-app purchases vs paid). On price and in-app purchases there is nothing between them.
