Verdict
The clearest difference is ads: Drifting Stone at none against Castle Defender's shown. Drifting Stone also leads on update cadence (monthly vs every 26 months) and ratings volume (13 vs 2). Castle Defender's advantage is rating (5.0 vs 4.7). On price, in-app purchases, monetization model and device support there is nothing between them.
