Verdict
The clearest difference is in-app purchases: King Duel at none against Highway Cleaner's 1. King Duel also leads on update cadence (every 4 days vs every 3 months). Highway Cleaner's advantage is ads (none vs shown). On price, device support and iOS requirement there is nothing between them.
