Verdict
The clearest difference is price: Know Notes at Free against Myrddin's $0.99. Know Notes also leads on rating (4.9 vs 4.1) and update cadence (fortnightly vs every 62 months). Myrddin's advantage is in-app purchases (none vs 6) and chart position (#56 vs unranked). On ratings volume and ads there is nothing between them.
