The clearest difference is price: Cosmic Robots at Free against Slaughter's $0.39. Cosmic Robots also leads on update cadence (weekly vs every 3 months) and iOS requirement (13.0 vs 15.6). Slaughter's advantage is ads (none vs shown). On in-app purchases and device support there is nothing between them.
