Verdict
The clearest difference is in-app purchases: Roulette Gun at none against Crazy John's 1. Roulette Gun also leads on update cadence (every 3 days vs every 4 weeks). Crazy John's advantage is ads (none vs shown) and iOS requirement (3.0 vs 13.0). On price and device support there is nothing between them.
