Verdict

The call

The clearest difference is update cadence: Proton VPN at every 2 weeks against SIMO's every 2 months. Proton VPN also leads on ratings volume (129K vs 3.4K) and chart position (#10 vs unranked). SIMO's advantage is iOS requirement (15.1 vs 17.0). On price, rating, review sentiment and ads there is nothing between them.
