Verdict
The clearest difference is review sentiment: Keep Browser at 100% against GalapaBrowser's 65%. Keep Browser also leads on update cadence (every 11 days vs monthly). GalapaBrowser's advantage is ads (none vs shown) and monetization model (free vs ad-supported). On price, in-app purchases and device support there is nothing between them.
