Verdict
The clearest difference is rating: Filen at 3.8 against EteSync's 3.0. Filen also leads on review sentiment (48% vs 20%) and ratings volume (123 vs 20). EteSync's advantage is monetization model (free vs freemium) and iOS requirement (10.0 vs 26.0). On price, update cadence, ads and in-app purchases there is nothing between them.
