Verdict
The clearest difference is in-app purchases: compilerFish at none against Walnut's 1. compilerFish also leads on ads (none vs shown) and iOS requirement (15.5.0 vs 18.4). Walnut's advantage is update cadence (every 4 days vs every 6 weeks). On price and device support there is nothing between them.
