Verdict
The clearest difference is rating: Pi Epsilon at 5.0 against Proton Drive's 4.1. Pi Epsilon also leads on in-app purchases (none vs 9). Proton Drive's advantage is update cadence (fortnightly vs every 6 months) and ratings volume (1.1K vs 4). On price, ads, device support and iOS requirement there is nothing between them.
