Verdict
The clearest difference is ads: ButterflyMX at none against KeyHelper's shown. ButterflyMX also leads on ratings volume (113K vs 1) and monetization model (free vs ad-supported). KeyHelper's advantage is update cadence (every 4 days vs fortnightly). On price, rating, in-app purchases and device support there is nothing between them.
