Verdict
The clearest difference is in-app purchases: Proton Authenticator at none against Standard Notes's 1. Proton Authenticator also leads on update cadence (weekly vs every 2 weeks). Standard Notes's advantage is rating (4.7 vs 4.4) and ratings volume (3.7K vs 242). On price, review sentiment, ads and device support there is nothing between them.
