Verdict
The clearest difference is price: ButterFlyer at Free against Rust IDE's $0.99. ButterFlyer also leads on rating (5.0 vs 2.5) and iOS requirement (13.0 vs 15.0). Rust IDE's advantage is chart position (#17 vs unranked) and ratings volume (6 vs 1). On update cadence, ads, in-app purchases and device support there is nothing between them.
