Verdict
The clearest difference is review sentiment: Resilio Sync at 78% against NAS Reader's 31%. Resilio Sync also leads on rating (4.5 vs 2.5) and ratings volume (844 vs 2). NAS Reader's advantage is ads (none vs shown) and monetization model (free vs free with in-app purchases). On price, update cadence, in-app purchases and device support there is nothing between them.
