Verdict
The clearest difference is in-app purchases: Project Function at none against FivePointFive's 5. Project Function also leads on device support (4 vs 2) and iOS requirement (15.5 vs 18.6). FivePointFive's advantage is update cadence (every 5 days vs every 6 weeks) and chart position (#83 vs unranked). On price and ads there is nothing between them.
