Verdict
The clearest difference is price: OCaml at Free against Rust IDE's $0.99. OCaml also leads on rating (4.6 vs 2.5) and review sentiment (64% vs 22%). Rust IDE's advantage is in-app purchases (none vs 3) and update cadence (every 9 days vs monthly). On ratings volume, ads, device support and iOS requirement there is nothing between them.
