Verdict

The call

The clearest difference is in-app purchases: StopGuide at none against CharacterKey's 6. StopGuide also leads on ads (none vs shown) and rating (5.0 vs 4.7). CharacterKey's advantage is update cadence (every 5 days vs fortnightly) and ratings volume (54 vs 4). On price, device support and iOS requirement there is nothing between them.
