Verdict
The clearest difference is ads: UNdata at none against World Factbook +'s shown. UNdata also leads on monetization model (free vs ad-supported) and iOS requirement (12.0 vs 15.6). World Factbook +'s advantage is ratings volume (81 vs 11) and review sentiment (62% vs 53%). On price, rating, update cadence and in-app purchases there is nothing between them.
